fix: add App Group state sync between mobile and lock app

[Takeru-Habu]

What

• Added a native SharedLockState bridge on the mobile app and write shared state to App Group on contract creation, refresh, and logout.
• Updated lock-app to read App Group shared values and refresh state when entering foreground.
• Added App Group entitlements to both targets and adjusted lock-app build settings for simulator compatibility.

Why

• Keep lock-app shield behavior synchronized with mobile dashboard usage/blocking state on the same device.
• Improve local verification by enabling simulator-friendly lock-app builds.
