The Add-Pair screen defaulted deleteBehavior to MIRROR for every direction,
so an Upload-only backup would delete cloud files when you deleted them on
the phone. Now the default follows the direction:
- Upload-only / Download-only -> KEEP (deleting locally leaves the cloud copy)
- Two-way -> MIRROR
All three options remain selectable; once the user explicitly picks one,
changing direction no longer overrides it, and editing a saved pair keeps
its stored choice. Adds RecommendedDeleteBehaviorTest.
Sync loop root-cause fixes (three independent bugs):
1. Folder change clears stale file states (AddPairViewModel): when
localPath or remotePath changes on an existing pair, all
SyncFileStateEntity records are wiped. Previously those stale records
caused every sync to attempt DELETE_REMOTE on the old folder's files
and to treat all new-folder files as changed — causing both the
"deleting 32 files" loop and rewrites on every run.
2. Download stores null localModifiedAt (SyncEngine): SAF document
cursors can return a stale mtime immediately after a write. Storing
null forces the SKIP reconciliation pass on the next sync to read
the actual walkFiles cursor value, breaking the download->changed->
download loop caused by mtime inconsistency.
3. Second-precision mtime comparison (syncDecide): WebDAV RFC-1123 has
1-second precision; FAT32 has 2-second precision. Comparing at
millisecond level caused phantom "changed" detections after syncing
to/from these systems. Now uses epochSecond for both local and remote.

- Sync icon now rotates (CSS-style spin) in StatusPill, StatusBanner,
and card sync button whenever status is SYNCING
- Launcher icon redesigned: indigo→violet→cyan gradient background,
upload arrow fades white→sky-blue, download arrow fades white→violet,
soft glow ring behind arrows
- Fix ON_CHANGE not triggering: FileWatchService.start() now called
from AddPairViewModel.save() so pairs created with ON_CHANGE
immediately begin watching without needing a toggle or reboot
- Fix FileWatch notification hidden: IMPORTANCE_MIN → IMPORTANCE_LOW
so the "Watching N folders" notification shows in the shade
