Add GET /support/swaps endpoint to expose swap statistics without authentication. Features: - Query all swap types (chain, submarine, reverse) - Filter by type, pair, direction, status - Returns aggregated stats (total, claimed, expired, refunded, pending, failed) - Returns detailed swap list with source/destination info New files: - swap-stats.dto.ts: DTOs for query params and response Modified: - support.service.ts: Added getSwapStats() with fetch/map methods - support.controller.ts: Added public GET endpoint
- Wrap DB queries in try-catch with proper error logging - Fix sorting to handle invalid dates (NaN fallback to 0)
- Fix toIsoString: handle objects safely, support numeric timestamps - Reduce cognitive complexity: extract matchesStatusFilter method - Use pattern lookup instead of switch statement
- Add optional chaining (?.) in stats calculations - Add nullish coalescing (?? '') in map functions - Prevent TypeError when DB returns NULL status
