Reported from a live install: the sensor showed ``ar.tvplayer.tv`` while the
media player showed "TiviMate" — the same foreground app, two identities.
The sensor's ``native_value`` returned ``manager.foreground_app`` (the raw
package push) or ``running_apps[0]["package"]`` as-is, while the media player
resolved names through apps map → cached manifest label → androidtv entity tier.
Both now call ONE function, ``resolve_app_name`` (media_player.py), so the two
entities cannot disagree again; the sensor keeps the raw package as its
``app_id`` attribute and ``app_name`` carries the shown name.
Per the contract:
* apps map wins, then the cached manifest label, then the androidtv entity's
``app_name``, then the package text itself;
* a bare or unknown package falls back to the package text, NOT None (it used to
be possible for the value to vanish while the app was plainly running);
* pinned by tests: map tier, label tier, entity tier, the ADB-recents source, the
unknown-package fallback, and sensor == media player for the same inputs.
Verified: 302 passed / 2 skipped, ruff clean.
