refactor(app): debloat 3.3.1 and fix startup restoration

Maintainer changes on top of PR #2 (Naveax). Reduces the release to two
deliberate connection modes and resolves the issues found in review:

- Lock-screen privacy: move VISIBILITY_PRIVATE and a generic publicVersion
  into MainActivity.updateVpnNotification. The PR's fix lived in an
  unreferenced class and never reached the live notification.
- Haptics: restore the default to off, and reduce HapticSettings to a
  single success() on connect/disconnect via the native channel.
- SOCKS5: make it a real proxyOnly local-proxy mode rather than a TUN
  connection under a different label. TUN stays the default.
- Health probe: restore the idle-only guard so /health is no longer polled
  every 30s while connected.
- Recovery: add a _connectionEpoch counter so connect() aborts an
  in-flight Extreme recovery.
- Startup restoration: rebuild the recovery snapshot from the still-active
  session after an app-process restart (TUN), and surface an honest
  orphaned state with a Reconnect action in proxy mode.

Drops per-app routing entirely. It only ever functioned in TUN --
addDisallowedApplication lives inside the VPN-interface setup that
proxyOnly skips -- and its allowlist half had no Dart caller.

Also removes flutter_local_notifications, the global tap-haptic surface,
and unused runtime telemetry.
