docs: note BIP39 cross-wallet restore parity is mainnet-only in -mnemonic help

Browse Source 
The 24-word seed restores the same wallet in SilentDragonXLite only on mainnet;
testnet/regtest derive a different HD coin_type (per BIP44), so a phrase does not
round-trip across wallets there. Document that in the -mnemonic help so it is not
mistaken for a bug.
