Pull request overview

This PR modernizes the “Recent changes” feature by replacing the legacy view-based Java Activity/RecyclerView implementation with a Kotlin + Jetpack Compose + Material 3 screen, including debug-only Compose previews for UI review without needing live Syncthing data.

Changes:

• Replaced the old RecentChangesActivity + RecyclerView adapter/layout/menu with a new Compose-driven RecentChangesActivity/RecentChangesScreen.
• Updated disk-event fetching behavior to avoid long-poll UI hangs by adding timeout=1 to the /rest/events/disk request.
• Added debug-only Compose preview tooling dependencies and a comprehensive preview suite.
