Rework the snapshot-converter into a command tree:

  - daemon:  watch a node's snapshot directory and convert each exported LSM
             snapshot into a Mem snapshot as it is produced
  - convert: one-shot conversion between an exported LSM snapshot and a Mem
             snapshot, in either direction
  - lsm export / lsm import: move snapshots out of / into an offline LSM
             database

Conversions operate only on standalone (exported) LSM snapshots and Mem
snapshots, never on a live database.

'mkLSMArgsIO' gains a 'Maybe Salt' so a node can create its LSM database with a
stable, configured salt (a fresh random one is used when 'Nothing').

db-analyser surfaces the LSM snapshot export directory via a new 'mkLSMConfig'
method on 'HasProtocolInfo' (read from the node config's
'LedgerDB.LSMExportPath'); it keeps using a random salt, as it builds a
throwaway ledger database whose exported snapshots record their own salt.

Some CIP-30 wallets (notably mobile in-app browsers) return addresses
from getChangeAddress/getUsedAddresses/getRewardAddresses as hex-encoded
CBOR bytes rather than bech32. WalletAuthModal passed that hex into
deserializeAddress, whose bech32 decoder threw a raw 'Invalid checksum'
error and broke wallet authorization. connect-wallet.tsx had the same
bug in its UTXOS payment/stake normalization blocks, silently swallowed
by try/catch, letting hex addresses flow into the user store.

Add normalizeAddressToBech32 (Address.fromBytes().toBech32() from
@meshsdk/core-cst), which derives the network from the address header
byte, and use it at all three sites. Surface a clear error in the auth
modal when the wallet address still cannot be parsed.

Reads the salt used when exporting from the `<exportedSnap>/salt` file.

Importing a snapshot requires the same salt that was used when exporting it. We
copy the `<session>/metadata` file into the exported snapshot as
`<exportedSnap>/salt` so that we can recover it.
