- Provides foundation for single-source-of-truth database functionality

This enhancement establishes the /api/services/check endpoint as the core service resolution system, enabling reliable provisioning operations across all UISP service lifecycle scenarios.

Added automatic config sync functionality to UISP admin interface. JavaScript automatically triggers sync operations when navigating to client/service pages, providing preemptive cleanup without requiring webhooks.

Implemented new /api/v2/configs/sync endpoint that provides centralized service resolution and config cleanup. This endpoint handles service_id updates, service_status synchronization, and deletion of orphaned configs based on UISP service data.

Created new /api/services/sync endpoint in the Plugin that forwards sync requests to the provisioner. Supports both specific service ID sync and bulk operations for all services.

Established the /api/services/check endpoint as the definitive single-source-of-truth for service chain resolution, implementing enterprise-grade bidirectional service traversal with complete lifecycle support.

## Core Architecture Improvements
- **Bidirectional Chain Resolution**: Complete ancestor and descendant service chain discovery using optimized SQL queries
- **Internal API Authentication**: Added request attribution system for internal controller calls to bypass external auth requirements
- **Enhanced Response Format**: Standardized API responses with correct, correct_status, should_delete, and complete chain data
- **Timing-Aware Logic**: Sophisticated DEFERRED service handling with effective_date calculations for future provisioning decisions

## Database Integration Excellence
- **Transaction Safety**: Atomic operations ensure data consistency during service resolution
- **Performance Optimization**: Database-level recursive queries minimize application-layer processing overhead  
- **Complete Field Coverage**: All critical UISP service fields (active_from, active_to, deleted_at, invoicing_start) fully supported
- **Chain Integrity**: Guaranteed complete service chain resolution with no missing links or orphaned services

## Business Value Delivery
- **Eliminated Config Orphaning**: Users no longer see empty configuration panels after service lifecycle changes
- **Automated Service Tracking**: System automatically follows service chains through supersession, pause, defer, and plan changes
- **Reduced Support Burden**: Proactive service resolution prevents user confusion and support tickets
- **Enhanced Data Reliability**: Single source of truth eliminates data inconsistencies across the platform

## Technical Foundation
This enhancement transforms service resolution from a reactive webhook-based system to a proactive, database-driven architecture that serves as the foundation for all provisioning operations. The recursive CTE implementation ensures complete service chain visibility while maintaining optimal performance through configurable recursion limits.

The system now provides enterprise-grade reliability for ISP provisioning operations, supporting complex service lifecycles with precision timing and complete audit trails.

Enhanced Plugin API endpoints to support internal controller calls via request attributes, eliminating the need to expose auth tokens for internal operations.

Updated sync endpoints to return detailed change tracking with old/new values for each updated field. Response format includes updated configs with old/new values and array of deleted config IDs.

Added unified json() helper method to BaseController that handles both array and string responses with automatic error formatting and status code management.

Fixed an issue where users could submit a config with an empty static_ip field even when the selected site had no auto-assignable IP blocks. The validation now dynamically checks if the current site has IP blocks with auto:true and available capacity. When switching sites, the static_ip field requirements update accordingly (optional vs required) and the field is automatically re-validated to ensure proper form validation state.

Implemented comprehensive bi-directional service ID resolution system that automatically handles all UISP service lifecycle changes including pause/defer, plan changes, supersession, deletion, and suspension/reactivation. The system ensures configs are properly updated or preserved based on timing and service status.

Implemented comprehensive service ID resolution integration across all critical application touch points, eliminating config orphaning and empty panel issues when UISP changes service IDs during lifecycle operations.

Integration points added:
• **Touch Point 1a**: Single service page resolution in /client/service/+page.server.ts prevents empty config panels on page load
• **Touch Point 2**: Provision endpoints batch resolution in /api/v2/provision ensures accurate provisioning with current service IDs  
• **Shared utilities**: Created resolveServiceIds() and resolveServiceIdsFromLocals() functions in configs.ts for consistent resolution logic
• **Batch processing**: Efficient single API call per batch instead of individual service lookups

Critical fixes:
• Fixed API authentication to use X-Auth-Token header consistently across all endpoints
• Implemented real-time service_id resolution before config display and provisioning operations
• Added comprehensive error handling and logging for resolution processes
• Enhanced in-memory config updates with database persistence for resolved service IDs

Performance improvements:
• Batch API calls reduce network overhead (1 call vs N individual calls)
• In-memory config updates before database operations improve provisioning speed
• Efficient updateMany() operations for bulk service ID corrections

This resolves the critical UX issue where users would see empty configuration panels after UISP service changes, ensuring seamless service management experience.

Fixed Playwright test fixture race condition in CI/CD by adding delay before context cleanup

Fixed critical bug where DEFERRED services (status 6) were being incorrectly deleted despite being valid future services. DEFERRED services represent scheduled future service activations and should not be removed from the system.

Key fixes:
• Prevented premature deletion of services with status 6 (DEFERRED) in service lifecycle processing
• Implemented timing-aware resolution logic to respect DEFERRED service activation schedules  
• Enhanced service validation to properly distinguish between expired and deferred services
• Added comprehensive logging for DEFERRED service status changes and resolution decisions

This resolves critical customer impact where legitimate future service configurations were lost, ensuring DEFERRED services are preserved until their scheduled activation dates.

Implemented comprehensive bi-directional service ID resolution that fixes critical UX issue where users would see empty config panels when UISP changed service IDs during pause/defer/supersede operations.

Key improvements:
• Fixed bi-directional SQL query in ServicesCheckController.php for backward chain resolution
• Implemented Touch Point 1a - Single service page resolution in client/service/+page.server.ts
• Implemented Touch Point 2 - Provision endpoints resolution in /api/v2/provision
• Created shared utility functions in configs.ts for service ID resolution
• Fixed API authentication to use X-Auth-Token header

This resolves the critical issue where service 2944 couldn't find the config created for service 2943, ensuring seamless user experience during service lifecycle operations.

Fixed critical issue where config panels would appear empty after UISP service changes. Implemented automatic page load resolution that cleans up orphaned configs and ensures pristine validation data.
