fix(android): remove WorkManager auto-initializer (lintVitalRelease)

The android.yml release build (run 110, job 282) failed at
lintVitalRelease with:

  AndroidManifest.xml:13: Error: Remove androidx.work.WorkManagerInitializer
  from your AndroidManifest.xml when using on-demand initialization.
  [RemoveWorkManagerInitializer from androidx.work]

MinstrelApplication implements androidx.work.Configuration.Provider
and supplies the HiltWorkerFactory, so WorkManager initializes
on-demand at first WorkManager.getInstance(...) call. The androidx-
startup InitializationProvider that ships with the work-runtime
library still auto-registers WorkManagerInitializer, racing the
on-demand path. Lint catches this as a release blocker.

Fix: merge the InitializationProvider entry and remove the nested
WorkManagerInitializer meta-data with tools:node='remove'. This is
the AOSP-recommended fix when an Application is its own
Configuration.Provider.
