Stage 17 #4: enrich the out-of-app your-turn push + add game-over

The Telegram 'your turn' notification now names the opponent and recaps their last
move (voiced as the opponent: «{name}: my move — «WORD». Score 120:95» for a scoring
play; a short 'swapped / passed, your turn' otherwise), and a new game-over
notification reports the result + final score when a game ends by any path (closing
play, all-pass, resign, timeout). Scores are recipient-first (the reader's score
leads), 2-4 players (120:95:80).

- schema: YourTurnEvent gains opponent_name/last_action/last_word/score_line
  (appended, backward-compatible); new GameOverEvent{result, score_line}. Go + UI
  bindings regenerated (flatc 23.5.26 + pnpm codegen).
- backend: notify.YourTurn enriched + notify.GameOver; emitMove resolves the mover's
  name and emits per-recipient (your_turn to the next mover, game_over to every seat),
  with recipient-first score lines built in one place.
- gateway: game_over joins the out-of-app whitelist (routing.go).
- connector: render builds the enriched your_turn + game_over text per language (en/ru).
- tests: notify round-trip (enriched + game_over), emit (enriched fields + game_over to
  all seats / per-seat result), connector render (en/ru), routing; integration replay
  (play → your_turn with real name; resign → game_over) green.
- docs: ARCHITECTURE push catalog + out-of-app set, FUNCTIONAL (+ _ru), PLAN tracker.
