Add Ledger support and Traditional Chinese localization

[giant9096]

Hello Macadamia Wallet team,

Thank you for developing such an innovative and smooth wallet! I especially enjoy the iMessage integration—it makes sending Bitcoin feel effortless and almost magical.

I have a couple of suggestions that could make Macadamia Wallet even more user-friendly:
1. Ledger support
Many users rely on Ledger hardware wallets for extra security. Adding Ledger support would allow those who prioritize hardware-level security to safely use Macadamia Wallet.
2. Traditional Chinese localization
Currently, the app is mainly in English. Adding Traditional Chinese would make it easier for users in Taiwan, Hong Kong, and other regions that use Traditional Chinese to navigate and enjoy the app.

Thank you for considering these suggestions!
