[DeckSync] Pass the sync summary through the signal and tidy the manager API

- Emit SyncSummary from syncFinished() instead of four positional ints, and
  build it from a single currentSummary() helper, so the counts cannot drift
  between the status message and the signal.
- Use a designated initializer for LocalFile, like the other records.
- Drop setClient() and setColorIdentityProvider(): both fields are already
  constructor parameters and the setters had no callers. setProfile() and
  setDeckPath() stay, since the tab re-reads them before every run.
- Fix the include paths in tab_deck_storage.h and the narrowing conversion of
  the tree item id, so the branch builds again.
