Adds a new `modules/miniMax` module mirroring the existing OpenAI
pattern (`api_key` + `enabled` config keys). Adds a
`classes/minimax.php` client that calls
`https://api.minimax.io/anthropic/v1/messages` (the same endpoint
OpenClaw's minimax-portal provider uses) and returns structured JSON via
the Anthropic tool_use response shape.
**Replaces the autopilot planner:**
- `PLANNER_MODEL`: `gpt-5.6-sol` → `MiniMax-M3`
- `xlvask_automation_service`: `new openai()` → `new minimax()` in the
planner + the isOpenAiIntegrationEnabled() guard
- New xlvask config flag `minimax_integration_enabled` gates the
autopilot. The OpenAI flag is kept so deployments can roll back.
**Compatibility shims** (so the autopilot keeps working with minimal
churn):
- `minimax_request_exception` extends `openai_request_exception`, so
every existing `catch (openai_request_exception)` block catches MiniMax
errors unchanged.
- The result payload also carries the legacy `_openai_response_model`
and `_openai_usage` aliases, so `sanitizeOpenAiResult` keeps working
unchanged.
**New endpoints:** GET/POST `/minimax/config` in `moduleConfigRoute`
guarded by `modules_minimax_config`, mirroring `/openai/config`.
**Tests:** PHP api suite 290/290 passing locally (no regressions). All
xlvask tests still pass.
**Frontend counterpart** ships in a separate PR on pleno-vue
(ConfigurationXLVask.vue + SessionUser.modules.minimax + i18n in all 5
locales).
**Followup (post-merge):** operator (jeppe) enters the MiniMax API key
in superuser XL Vask settings → I'll optimize/test/debug live XL Vask
usage logs against the new model.
