POC Hyprspace Android UI

[X4mp]

A minimal two-tab Android app (Jetpack Compose + Material 3) for managing a Hyprspace node:

• Identity tab — displays your node's peer ID, private key (hidden by default, biometric-gated reveal), and VPN addresses. Tap the copy icon to copy any field; long-press the peer ID for the full value.
• Peers tab — lists configured peers, swipe left to delete (with confirmation), tap + to add a new one via a bottom sheet with peer ID validation.
• Config is persisted as a single JSON file in internal storage; a fresh key and peer ID are generated on first launch.
• A third Connection/VPN tab slot is stubbed out for the future VpnService integration.
