Detect Bitcoin on-chain transactions and display them differently
from Lightning transactions in the wallet viewer. Bitcoin transactions
show Transaction ID with a link to mempool.space for blockchain
exploration.
Detection:
- Bitcoin txid is 64-character hex string in preimage field
- Uses regex validation to detect on-chain transactions
Display changes:
- Bitcoin: Show "Transaction ID" with mempool.space link
- Lightning: Show "Payment Hash" and "Preimage" as before
- Network-aware: Links to testnet/signet explorers when applicable
