Reset Macaroon in UI

[jimbrend]

The ability to reset admin macaroon from UI, likely may need to trigger an lncli create command
confirm password and mnemonic phrase, and generate a new one

with a warning it may disconnect other connected wallets that are using liquidity

yes, we need this !! Thank you

Connecting umbrel node to external wallets like Zeus is always scary as there is no easy way to reset the admin macaroon and disconnect all external wallets for security.
