fix(api): resolve Sentinel serialization, missing params, and add search endpoint (#80)

Fix multiple issues with the REST API that caused downloads to fail: - Filter Click Sentinel.UNSET enum values from service parameter defaults that caused "Object of type Sentinel is not JSON serializable" errors - Add missing select_titles and no_video args to dl.result() call - Fix wanted param unpacking for list-tracks SeasonRange.parse_tokens() - Add enum conversion for vcodec, range, sub_format, and export params that were passed as strings but expected as enums by dl.result() - Add missing dl command params: split_audio, repack, imdb_id, output_dir, no_cache, reset_cache to DEFAULT_DOWNLOAD_PARAMS and download worker - Expand vcodec/acodec/sub_format validation to cover all supported values - Add POST /api/search endpoint for searching services by query - Update Swagger docs with all new params and correct type definitions - Add comprehensive REST API documentation (docs/API.md) - Update ADVANCED_CONFIG.md with serve CLI options and API reference

+# REST API Documentation
+
+The unshackle REST API allows you to control downloads, search services, and manage jobs remotely. Start the server with `unshackle serve` and access the interactive Swagger UI at `http://localhost:8786/api/docs/`.
+
+## Quick Start
+
+```bash
+# Start the server (no authentication)
+unshackle serve --no-key
+
+# Start with authentication
+unshackle serve  # Requires api_secret in unshackle.yaml
+```
+
+## Authentication
+
+When `api_secret` is set in `unshackle.yaml`, all API requests require authentication via:
+
+- **Header**: `X-API-Key: your-secret-key-here`
+- **Query parameter**: `?api_key=your-secret-key-here`
+
+Use `--no-key` to disable authentication entirely (not recommended for public-facing servers).
+
+```yaml
+# unshackle.yaml
+serve:
+  api_secret: "your-secret-key-here"
+```
+
+---
