test(config): pin the Jellyfin name tiers and the address redaction (t41)

Two acceptance items that had no test of their own:

* the Jellyfin auto-detect tiers. t41 replaced the entity-derived search key
  (the Android TV Remote entity's friendly_name) with the names setup already
  knows — the name the user typed, then the discovery device name. Three tests
  pin it, the third being the regression: a Jellyfin player matching the *atv*
  friendly_name, with a serving state, used to be auto-detected; now only the
  typed/discovered names search. Red proof on the pre-t41 tree (60d884b):
  `_find_jellyfin_entity(hass, "jellyfin shield")` DID match
  media_player.jellyfin_shield there.

* diagnostics redaction of the renamed address field. The G14 field list already
  carried "host" (alongside the legacy spellings), but the test only exercised
  the legacy keys — so a future edit could have dropped the live one unnoticed.
  The fixture and assertion now cover both spellings.

Verified: 337 passed / 2 skipped, 338 / 1 with androidtvremote2, ruff clean.
