Requirements for End-User LN Plugin

[Yuri-SVB]

1. App / Plugin establishes LN channel with our server (see server repository);
2. App / Plugin is able to securely send and receive messages to / from server;
3. App / Plugin integrates with main app (t3-vault);
4. Said integration will include: sending of TLP input, receiving of TLP output, memorization assistance for seed, backing up LN state in the encrypted state;
5. App / Plugin has to be able to both generate a vanilla self-custodial LN wallet and import an existing one;
6. Needless to say: try to minimize 'wheel reinvention'. Search options of existing LN wallets to fork from;
7. Password-protect;
8. Notifications for sending and receiving TLP-related content;
9. Show balance, and calculate fee and prompting user for confirmation before sending;
