test(api): wire up real mysqli in SchemaHealthCheckTest (TRU-77 unit CI)

The Unit suite starts with a freshly-dropped test database and does
not create a $db global, so:

- customer_invoice_email_schema_bootstrap::ensureSchema() short-
  circuited and never created the users table.
- runSchemaCheck had nothing to inspect and reported ok=false.

Wire up a real mysqli connection at file load time using the same
CONFIG_DB_* env vars the rest of the CI suite exports, then have
beforeEach run the bootstrap and create the bare-minimum invoices /
bookings tables that runSchemaCheck verifies. This keeps the test
self-contained inside the Unit suite without changing the
production code or the production schema.

+# Default branch protection
+
+`master` is changed through pull requests. Do not push or publish directly to
+the default branch, including through automation or the Git Data API.
+
+## Normal publishing flow
+
+1. Create a scoped `agent/*` or feature branch from the current `origin/master`.
+2. Commit and push only the intended changes.
+3. Open a pull request targeting `master`.
+4. Wait for the `Required CI` check. If `master` moves, update the branch and
+   wait for the strict check to rerun.
+5. Resolve every review conversation and squash-merge the pull request.
+6. Confirm the post-merge `Release Manager gate` completes on `master`.
+
+The aggregate check covers the PHP unit, integration, API, and legacy matrix,
+plus Edge Agent, Edge Broker, and Edge Gateway Backend. Qodana is advisory and
+the Release Manager gate is intentionally post-merge.
+
+## Desired ruleset
+
+[`rulesets/protect-default-branch.json`](rulesets/protect-default-branch.json)
+is the importable final desired-state repository-ruleset request body. For the
+initial POST, copy the file and override `enforcement` to `disabled`. Inspect
+the normalized ruleset and verify a green preparation PR and post-merge run,
+then PUT the exact committed file to activate it.
+
+The desired rule targets `~DEFAULT_BRANCH`, requires pull requests with zero
+approvals, conversation resolution, strict `Required CI` from GitHub Actions
+integration `15368`, squash-only linear history, and blocks deletion and force
+pushes. Repository administrators receive pull-request-only bypass; they do not
+receive a standing direct-push bypass.
+
+When the ruleset is activated, align repository settings at the same time:
+retain squash merging, disable merge commits and rebase merging, enable
+auto-merge and branch-update suggestions, delete merged branches automatically,
+keep the Actions token read-only, and prevent Actions from approving reviews.
+
+## Activation record
+
+Repository ruleset `19041620` was activated on 2026-07-16 after preparation
+PR #311 passed `Required CI` and the merged `master` commit passed both
+`Required CI` and the `Release Manager gate`. This documentation update is
+the after-activation canary for the normal protected pull-request path.
+
+## Break glass
+
+When an incident cannot wait for the normal gate:
+
+1. Open a pull request and describe the incident, risk, and reason for bypass.
+2. Have a repository administrator use the pull-request-only bypass.
+3. Monitor `Required CI` and the post-merge Release Manager workflow.
+4. Open a follow-up pull request for any deferred validation or remediation.
+
+Never bypass by updating `refs/heads/master` directly. Ruleset changes and
+emergency bypasses must remain visible in GitHub's audit trail.

+# XL Vask Selvvask surface — inventory & simplification plan
+
+## Scope
+
+The XLVask surface that powers the **Superuser → Fakturaer → Periode → Selvvask**
+view. Goal: remove the AI / MiniMax / autopilot pipeline, leaving only the
+operator-facing review and order-creation flow.
+
+Out of scope: any other XLVask, plate scanner, customer, or vehicle surface.
+
+## Files removed
+
+| Path | Reason |
+| --- | --- |
+| `services/nginx/app/classes/xlvask_autopilot_service.php` | AI autopilot pipeline |
+| `services/nginx/app/classes/xlvask_automation_service.php` | AI automation pipeline |
+| `services/nginx/app/classes/xlvask_automation_policy_service.php` | AI policy service |
+| `services/nginx/app/classes/minimax.php` | MiniMax integration |
+| `services/nginx/app/modules/miniMax/` | MiniMax module (config + class) |
+| `services/nginx/app/modules/xlvask/AUTOMATION_RUNBOOK.md` | Runbook for removed pipeline |
+| `services/nginx/app/modules/xlvask/cron/tasks.php` | Module-owned cron registry (replaced by empty `cron_task_registry` discovery) |
+| `services/nginx/app/modules/xlvask/migrations/20260804_xlvask_ai_auto_policy_v2.php` | Migration for removed AI schema |
+| `services/nginx/app/modules/xlvask/config/xlvask_automatic_order_attachment_enabled_c.php` | Legacy autopilot gate |
+| `services/nginx/app/modules/xlvask/config/xlvask_automatic_order_creation_enabled_c.php` | Legacy autopilot gate |
+| `services/nginx/app/modules/xlvask/config/xlvask_minimax_integration_enabled_c.php` | MiniMax gate |
+| `services/nginx/app/modules/xlvask/config/xlvask_openai_integration_enabled_c.php` | OpenAI gate |
+| `services/nginx/app/cron/EnsureXLVaskAutomationSchema.php` | Migration helper |
+| `scripts/xlvask-automation-migrate.php` | CLI wrapper for migration |
+| `services/nginx/app/tests/Unit/XLVask/XLVaskAutomationMigrateScriptTest.php` | Removed migration test |
+| `services/nginx/app/tests/Unit/XLVask/XLVaskAutomationServiceTest.php` | Removed automation test |
+| `services/nginx/app/tests/Api/XLVaskReviewApiTest.php` | Replaced by Selvvask route contract test |
+
+## Code changes (kept & simplified)
+
+| Path | Change |
+| --- | --- |
+| `services/nginx/app/cron/Cron.php` | Drop `ProcessXLVaskAutopilotQueueCron` registration + function |
+| `services/nginx/app/cli.php` | Drop `xlvask-automation-migrate` case |
+| `services/nginx/app/routes/moduleConfigRoute.php` | Drop `/minimax/config` GET/POST endpoints |
+| `services/nginx/app/routes/moduleXLVaskRoute.php` | Drop `/modules/xlvask/tasks/import-usage` 410 stub and `/tasks/debug` route |
+| `services/nginx/app/routes/xlvaskUsageLogsRoute.php` | Slim to operator-only: list, summary, ignore/unignore, accept, reject, fast-link |
+| `services/nginx/app/modules/xlvask/helpers/xlvask_tasks.php` | Drop `runScheduledAutomationIfReady`, `processAutopilotQueue`, autopilot cleanup, legacy auto-creation branch |
+| `services/nginx/app/modules/xlvask/xlvask_c.php` | Drop `minimax_integration_enabled`, `automatic_order_attachment_enabled`, `automatic_order_creation_enabled`, `openai_integration_enabled` |
+| `services/nginx/app/objects/xlvask_usage_logs_o.php` | Add `summarizeUsageOrdersReadOnly` (replaces autopilot summary) |
+| `services/nginx/app/openapi.yaml` | Replace autopilot/automation openapi block with operator-flow endpoints |
+| `services/nginx/app/tests/Unit/Cron/CronTaskRegistryTest.php` | Update count: 24 → 22, drop `xlvask.autopilot_queue` assertion |
+| `services/nginx/app/tests/Unit/XLVask/XLVaskUsageRouteContractTest.php` | Replaced with end-to-end contract assertions for the new operator surface |
+
+## New operator-facing endpoints
+
+All under `routes/xlvaskUsageLogsRoute.php` and scoped to the operator's
+`allowedHallIds` (all-scope users see every configured scanner hall; own-scope
+users see only their group's halls).
+
+| Method | Path | Permission | Purpose |
+| --- | --- | --- | --- |
+| `GET` | `/modules/xlvask/services/usage/orders` | `list_xlvask_usage_orders_own/all` | List usage logs with direct linked order id, amount summary, ignored metadata |
+| `GET` | `/modules/xlvask/services/usage/orders/summary` | `list_xlvask_usage_orders_own/all` | Read-only per-period summary (counts + net amount) |
+| `PATCH` | `/modules/xlvask/services/usage/orders/{id}/ignore` | `review_xlvask_usage_order` | Mark ignored with reason |
+| `POST` | `/modules/xlvask/services/usage/orders/{id}/unignore` | `review_xlvask_usage_order` | Clear ignored metadata |
+| `POST` | `/modules/xlvask/services/usage/orders/{id}/accept` | `review_xlvask_usage_order` | Convert to order via `createOrderFromWash` |
+| `POST` | `/modules/xlvask/services/usage/orders/{id}/reject` | `review_xlvask_usage_order` | Mark ignored with reject reason |
+| `GET` | `/modules/xlvask/services/usage/orders/fast-link` | `list_xlvask_usage_orders_own` | Cached fast-link redeem (existing) |
+
+## Permissions
+
+The Selvvask surface uses these permissions only:
+
+- `list_xlvask_usage_orders_own`
+- `list_xlvask_usage_orders_all`
+- `review_xlvask_usage_order`
+
+`manage_xlvask_usage_automation`, `ignore_xlvask_usage_order`,
+`superuser_xlvask_automation_activate` are not referenced anywhere in the
+slimmed surface.
+
+## Persistence model
+
+`xlvask_usage_logs_o` already exposes `ignored_at`, `ignored_by`, `ignored_reason`
+columns — no migration required for the simplified flow.
+
+`orders_o::selectByWashId(int|string $WashId)` and
+`orders_o::addXLVaskOrder(users_o $user, xlvask_usage_log $xlvask_usage_log)` are
+the only integration points with the order pipeline.
+
+## Tests
+
+- `vendor/bin/pest --testsuite=Unit --colors=never` passes 1266 tests.
+- One pre-existing failure (`BirdControlPlaneActivationTest`) requires
+  `PLENO_REPO_ROOT_FOR_TESTS` (coolify repo) and is unrelated to this change.
+
+## Repo scope
+
+This inventory covers `api`. The `pleno-vue` side has not yet been updated in
+this session and will be handled in a follow-up PR.
