Splash gates the app while Foldergram indexes

Foldergram is unusably slow during a scan, so the splash (renamed from
LockActivity) now shows on every start and return to the app: PIN if
set, then it polls /api/scan-progress every 5 s and stays on "Library
is indexing" until the scan ends. Home connects only after the splash.
Builds and deploys; the indexing path is not yet tested on the TV.
