chore: clear out what the own-store branch left behind, and refresh deps

Dead weight, found by reading `lintDebug` rather than by anything breaking.

Gone with the deleted `:provider` module: its entire dependency block in the
version catalog — jems, rfc5545-datetime, Robolectric, JUnit 4, Hamcrest,
Mockito — plus the comments explaining a `provider/PROVENANCE.md` that is not
there any more. Only lib-recur survived the deletion and it is now documented
where it lives. That block was also the source of most of the catalog's
"newer version available" noise.

Gone outright: `glance-appwidget` and `glance-material3`, declared but not
referenced by a single line, so they were shipping in the APK for nothing. The
WorkManager `ListenableWorker` keep rule went with them, since Glance was what
dragged WorkManager in; the RoomDatabase keep rule stays and its comment now
says why it matters *more* than it did — Room used to arrive transitively
through that chain, and is now our own task store.

Also gone: thirteen unused resources (twelve strings and a colour), which
volunteers on Weblate were translating for nothing; a `SDK_INT < O` branch that
cannot be false at minSdk 29; and the `-v26` qualifier on the mipmap folder,
unnecessary at the same minSdk.

`DemoSeeder` is injected as a `Provider` now. Its call site is
`BuildConfig.DEBUG`-gated, i.e. compile-time dead in a release build, but
injecting the instance still constructed one on every launch of the shipped
app.

`ProviderChangeReceiver` gets one intent-filter per authority rather than two
`<data>` tags in one filter. Identical behaviour — Android takes the cross
product of every data attribute in a filter — but it no longer reads as if it
might not, which is what lint's IntentFilterUniqueDataAttributes warns about.

Dependency refresh, app-level only: KSP 2.3.11, Hilt 2.60.1, lifecycle 2.11.0,
material3 1.5.0-alpha26, JUnit 6.1.3, hilt-navigation-compose 1.4.0. That last
one moved `hiltViewModel` into `androidx.hilt.lifecycle.viewmodel.compose`, so
nine call sites follow it and the artifact it now lives in is declared rather
than inherited. The floret-kit coordinates move into the catalog, version-less,
since the composite build substitutes them.

Deliberately not touched: AGP, Gradle, Kotlin, the Compose BOM and
kotlinx-* — toolchain moves that want their own change and a
reproducible-build check, not a release cut. lib-recur stays pinned at 0.12.2
(0.16.0 removed `RecurrenceSet`).
