* remove LNC FIXMEs
Mhh, I guess the TURN server was down or something? It now magically works. Or maybe it only works once per mnemonic?
* also removed the lnc.lnd.lightning.getInfo() call since we don't ask and need permission for this RPC for payments.
* setting a password does not work though. It fails with 'The password provided is not valid' which is triggered at https://github.com/lightninglabs/lnc-web/blob/main/lib/util/credentialStore.ts#L81.
I moved the schema for lnbits, nwc and lnc out of lib/validate only to put them back in there later.
This commit should make the changeset cleaner by removing noise.
