Migrate Android Auto implementation to androidx.car.app:app:1.7.0

Updates the Android Auto code path to the androidx.car.app:app:1.7.0
contract. The bulk of this PR is the 1.7.0 contract alignment from
#2008; the MediaPlayerService / TelegramMediaSession
integration is a follow-up added by risin42 in
risin42/NagramX@ec956e3 ("fix: Android Auto support", co-authored by
rainman74).

The AndroidX media-compat artifact androidx.media:media:1.7.0 keeps its
classes under the legacy android.support.v4.media.* package for binary
compatibility reasons - the import migration to androidx.media.* is
NOT applied here (it would reference non-existent classes). Only the
new transitive dependency is added; existing android.support.v4.media.*
imports are left as-is.

Build
- bump androidx.car.app:app:1.4.0 -> 1.7.0
- drop androidx.car.app:app-projected:1.4.0 (upstream pre-1.7.0 used
  the projected variant; the 1.7.0 line no longer needs it as a
  separate dependency)
- add androidx.media:media:1.7.0 (AndroidX media session)
- add androidx.lifecycle:lifecycle-runtime:2.7.0 (DefaultLifecycleObserver)

Manifest / config
- uncomment the CarAppService <meta-data> + <service> block in
  AndroidManifest.xml; bump minCarApiLevel 5 -> 7 (required by
  ConversationItem @RequiresCarApi(7))
- automotive_app_desc.xml: add <uses name="media"/> for the new
  CarAppService media category; keep notification and template

Code
- HomeScreen: ensure Person always carries a key, which the 1.7.x
  ConversationItem.validateSender() requires. Applied locally to the
  senderBuilder.setName("") branch in buildCarMessage, matching the
  upstream intent without touching the surrounding code.
- MusicPlayerService: after every mediaSession.setPlaybackState() and
  mediaSession.setMetadata(), also publish the same state / metadata
  to TelegramMediaSession so the MediaBrowserService is in sync with
  the phone player. On onDestroy, publish STATE_STOPPED if nothing is
  playing. Without this, the Android Auto media surface had no view of
  what the phone player was doing.
- TelegramMediaSession.publishPlaybackState: merge getAvailableActions()
  (skip next/prev, set shuffle, etc.) into the state before publishing,
  so Android Auto renders the full action set.

Upstream-specific context
- This PR adds the risin42/NagramX@ec956e3 MediaPlayerService /
  TelegramMediaSession integration on top of the original #2008
  contract alignment, so all three repos (upstream / NagramXF / NagramX)
  are in sync. The ec956e3 version of MusicPlayerService.java is NOT
  copied verbatim because DrKLO's upstream code has additional
  MIUI-specific lock-screen logic and an accountLogin handler that
  NagramX does not carry; the four targeted hunks (publishPlaybackState
  after each setPlaybackState, publishMetadata after setMetadata, and
  STATE_STOPPED cleanup in onDestroy) are applied on top of DrKLO's
  current file instead.
- Final diff against master: 6 files, 23 insertions(+), 10 deletions(-).
