Support Ledger Hardware Wallet Connection on Jup Mobile (Android)

Currently, Jup Mobile does not support connecting to a Ledger hardware wallet on Android devices. This limits users who prioritize security and use Ledger for mobile DeFi interactions.

Proposed Solution:
Enable Ledger support for Android via Bluetooth (Ledger Nano X) or USB OTG connection (where applicable). This would align with standard wallet practices in Web3 and expand access for mobile-native users who rely on hardware wallets.

Why it Matters:

• Increases mobile access for security-conscious users

• Brings Jup Mobile on Android closer to feature parity with iOS

• Encourages safer on-the-go trading and participation in governance
