Implement GET and POST/PATCH /api/settings endpoints with: - GET /api/settings: Returns all configurable settings as JSON with default values merged in for any settings not explicitly set - POST/PATCH /api/settings: Partial update with merge semantics, only updating the keys provided in the request body - SQLite persistence: Settings stored in settings table with JSON-encoded values, loaded on startup - Comprehensive validation: All known settings validated with proper range checks (fusion_rate_hz, grid_cell_m, delta_rms_threshold, tau_s, fresnel_decay, n_subcarriers, breathing_sensitivity, motion_threshold, dwell_seconds, vacant_seconds, max_tracked_blobs, replay_retention_hours, replay_max_mb, security_mode, events_archive_days) - OpenAPI-style godoc comments: Documentation for all endpoints using swagger annotations - Table-driven tests: Comprehensive test coverage for all functionality including GET, POST, PATCH, validation, persistence, and error cases - Helper utilities: Extracted writeJSON, writeJSONError, writeJSONData to utils.go for reuse Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
