fix(ios): PERMANENT native safe-area + keyboard via Capacitor 7 + safe-area plugin

Device screenshots proved the WebView reports env(safe-area-inset-*)=0, so no web/CSS/JS trick can
move content off the Dynamic Island — it must be fixed natively. Upgrade the Capacitor shell to v7 and
add @capacitor-community/safe-area (populates env() with real per-device insets, edge-to-edge) and
@capacitor/keyboard (resize:native so the composer sits directly on the keyboard, like Teams).

- mobile: Capacitor 6 -> 7 for all plugins; add safe-area + keyboard; SafeArea/Keyboard config.
- codemagic: npm ci -> npm install (dependency set changed); drop stale Cap6 lockfile.
- web: remove the temporary StatusBar/34px hacks (env() now works); keep var(--sat)/var(--sab) padding.
- share/connect: back link now respects env(safe-area-inset-top/left).
- add native-style slide in/out (push/pop) animation when opening/closing a chat on mobile.
Build marker -> 2026-07-17-batch92.
