refactor(api): replace new Logger() with DI LoggerService and split large files

- Migrate 30 files from `new Logger(ClassName.name)` to injected LoggerService
  for consistent PII masking and centralized logging config
- Split prisma-admin-query.repository.ts (313→121 lines) into admin-stats.queries.ts
  and admin-user.queries.ts
- Split admin.controller.ts (285→154 lines) into admin-moderation.controller.ts
- Split prisma-listing.repository.ts (274→111 lines) into listing-read.queries.ts
- Update 28 test files with mock LoggerService
- All 831 tests passing, zero direct new Logger() calls remaining
