Implement @EndpointRateLimit() decorator and EndpointRateLimitGuard for
granular per-endpoint rate limiting using a Redis sorted-set sliding window.
This prevents brute force attacks on auth endpoints, replay attacks on
payment callbacks, and scraping on search endpoints.
Applied rate limits:
- /auth/login: 5 req/min per IP
- /auth/register: 3 req/min per IP
- /listings POST: 10 req/min per user
- /search: 30 req/min per user
- /payments/callback/*: 100 req/min per IP
Features:
- True sliding window (sorted set) for accurate rate measurement
- Configurable key strategy (IP or authenticated user)
- Admin bypass support (enabled by default)
- Fail-open on Redis errors
- Proper 429 response with Retry-After header
- Rate limit headers (X-RateLimit-Limit/Remaining/Reset)
- 22 unit tests covering all scenarios

- FileValidationPipe now supports maxSizeByMimeType for per-MIME-type size limits
- Images: max 10MB, Video (MP4): max 100MB
- Oversized files return 413 Payload Too Large instead of 400 Bad Request
- MIME type validation runs before size check for clearer error messages
- Multer module limit raised to 100MB (per-type enforcement in pipe)
- Added 413 ApiResponse to Swagger docs on upload endpoint
- Added comprehensive unit tests for FileValidationPipe (16 test cases)

Install @nestjs/swagger, configure Swagger UI at /api/docs with JWT bearer
auth, and add ApiTags/ApiOperation/ApiResponse/ApiProperty decorators to
all 8 controllers (50+ endpoints) and 31 DTOs across auth, listings,
search, payments, subscriptions, admin, notifications, and analytics modules.
