Refactor Seed+SCB recovery/rescan

Recovering from seed (& SCB) needs a refactor. The idea is here to put the lnd & cl into a recovery mode where they are the started everytime with resetting on-chain transaction history and going into rescan when booted/restarted until they run trhu one time in a row and then get set back to normal mode.

So the scripts lnd.backup.sh & cl.backup.sh with get an recovery option for mainnet/testnet/signet and the background process will check for the recovery to finish.

Notes for lnd:

lncli getrecoveryinfo 
lnd --reset-wallet-transactions

When running the LND-REPAIR and REST with SEED+SCB I got the following error message after uploading the SCB:

WALLET --> UNLOCK WALLET - SCAN 0
WALLET --> SEED + SCB
StatusCode.UNKNOWN
/dev/fd/63: line 4: /home/admin/.lnd/data/chain/bitcoin/mainnet/admin.macaroon: Permission denied
lnd-wallet-seed+scb lnd.initwallet.py scb returned error /home/admin/config.scripts/lnd.initwallet.py scb mainnet ... --> RPCError RestoreChanBackupRequest + the RPC server is in the process of starting up, but not yet ready to accept calls

and as for first test … the “rescan” afterthis does not finish - will keep runnnig over night to see results.

The problem is that the macaroon owner is bitcoin:bitcoin and root (doing the background scan) is not in group bitcoin. Will add root user to group bitcoin in beginning of background.scan script.
