Introduces the pmourlsource crate as a standard MusicSource that resolves HTTP/HTTPS URLs via a priority-ordered UrlHandler registry. Includes specialized handlers for Qobuz and Radio France alongside an SSRF-safe generic scraper supporting playlists, feeds, and HTML audio. Integrates with existing browse flows, REST endpoints, and Android Web Share targets while updating source capability flags to correctly route URL queries.
Replaces raw string queries with structured `SearchQuery` types across the `MusicSource` trait and UPnP handlers. Adds dedicated paginated endpoints, explicit caching, and type-specific filtering for the Qobuz source. Fixes a frontend navigation bug by aligning state management with UPnP browse semantics and properly routing virtual container IDs. Also updates the Makefile for dynamic `RUST_LOG` configuration, standardizes logging with `tracing`, and adds the dependency lockfile.
- Prefix `_object_id` parameter with underscore to silence unused variable warning in `get_item`
- Add #[allow(unused_must_use)] to all action macro definitions in pmoupnp/macros.rs
- Remove redundant doc comment line break
