Do not treat managed aliases under disabled providers as usable Desktop routes. Match each route against its source on an enabled provider, skip disabled sources when creating aliases, and exclude disabled mappings when identifying direct aliases.
Validation: four regression tests fail before the fix and pass afterward; cargo test --locked (456 passed); cargo check --locked. After migrating the two affected live routes to the existing enabled source, Haiku and Opus messages requests both returned HTTP 200.
