Transitioned from obsolete gateway object classes (`edge_gateway_shell_action_jobs_o`, `edge_gateway_shell_events_o`, `edge_gateway_shell_sessions_o`, `edge_gateway_update_jobs_o`) to the new agent implementation (`edge-gateway-agent/agent.php`).
This commit introduces delivery metadata tracking for gateway commands, updates, and shells. Adds preferred delivery channel handling, refined validation for edge agents, improved relay management logic, and broker presence reporting. Includes schema changes, enhanced shell handling, and test coverage.
- Introduced `safety_seal` column in the `orders` table.
- Updated order creation and completion logic to handle safety seal values.
- Enhanced order and booking classes to manage safety seal attachment and retrieval.
- Added tests to validate safety seal functionality in order processing.
- Added support for `today`, `week`, and `month` progress tracking in `GoalsCriteria`.
- Introduced `setTimeframeByName` method to manage time-based progress criteria.
- Enhanced `calculateProgressFromArray` and `calculateProgressDetailsFromArray` to include customizable timeframes.
- Updated departmental progress calculations with detailed breakdowns for multiple time periods.
- Replaced obsolete single-value progress tracking with comprehensive progress details.
- Introduced calculation of departmental progress for today, week, and month in `department_goals_o.php`.
- Removed unnecessary blank line in `object_property.php` for code clarity.
- Refactored department daily targets logic for optimization and better maintainability.
- Ensured department-specific targets are validated, sanitized, and consistently applied in updates.
- Improved database interaction safety by preventing unnecessary updates for unchanged object properties.
- Adjusted route and API behavior for criteria and department updates to handle validations comprehensively.
- Introduced `department_daily_targets` field in criteria, renderer, and API to define daily target overrides for departments.
- Enhanced daily target logic to honor per-department overrides while maintaining backward compatibility.
- Updated SMS, email, and Slack renderers for consistent enforcement of text length limits with fallback to non-mbstring functions.
- Refactored order item update logic to improve database interaction safety by using setters.
- Introduced Redis-backed caching for user and subuser permission evaluations in the `route_t` trait, reducing database queries.
- Enhanced `Redis` class with methods for permission caching: `cache_permission`, `get_permission`, and `clear_permission`.
- Added test coverage for the new caching logic in `PermissionRedisCacheTest.php`.
- Implemented Redis caching for authentication sessions with `cache_auth_session`, `get_auth_session`, and `clear_auth_session`.
- Improved CORS handling for preflight requests in `index.php`.
- Removed all language pack-related files, traits, and classes.
- Enhanced `users_o.php` with Redis caching for mapping `customer_number` to `user_id` and vice versa.
- Added Redis checks and caching for improved performance in user retrieval methods.
