Module favorites 

Pushing favourite toggles made while the server was unreachable.

Favouriting works offline: storage_toggle_favorite writes the local user_data row and sets pending_sync = 1. Until DR-120 nothing ever cleared that flag — the offline mark_favorite/unmark_favorite are no-ops and syncService.queueFavorite had no callers — so an offline toggle was silently lost.

The drain lives in Rust, not the frontend, because it must run whether or not any view is mounted; a drain started by a component dies with it.
