feat(04-04): the destination resolver — two carriers, one validation, memory only

- resolve-destination.ts: reads ?dest= (URL, primary — the inline
  web_app-button carrier) then initData's start_param (the signed
  string, secondary — the direct-link/home-screen carrier), ONE
  slug validation, dest_ prefix stripped; resolves against the
  webview's own build-time @araharah/search copy; honest null for
  unknown ids; module-scope memory-only holder (GEO-03/D-07)
- destination-card.ts: the confirmation + honest-unavailable cards,
  createElement/textContent only, existing theme classes (T-04-32)
- webapp.ts: TelegramWebAppLike gains startParam, addToHomeScreen?,
  checkHomeScreenStatus? + HomeScreenStatus (Bot API 8.0+ members)
- telegram-mock.ts: satisfies the extended contract in the same
  change (startParam initData wiring, homeScreenStatus, __homeScreenAdded)
- strings.ts: 5 new copy fields in en+ms; web depends on @araharah/search
- DP1-DP12 green (45/45 web suite), web:typecheck green
