Fix L16/L75/L77: datetime formatting, update-token visibility, ffmpeg re-check

L16: relTime now caps at weeks/months instead of unbounded 'N d ago' (adds w/mo
     buckets). formatWhen omits the year when the timestamp is in the current year.
L75: Update-token Field in the Software-update card is hidden by default; only
     shown when a token is already configured or an update-check error occurred.
L77: Adds a Re-check button next to the ffmpeg/ffprobe version display so a
     previously-not-found binary can be re-detected without restarting the app.

typecheck + 242 tests + eslint + prettier green.
