refactor(broadcast-channel): extract response status registries from switch/case

Replace 11 repetitive switch/case blocks in commandResponseToResponseStatus
with two static registries:
- emptyResponseCommands: Set of commands where empty response = success
- acceptedStatusCommands: Map of commands to status check predicates

Custom cases (AUTHORIZE, START/STOP_TRANSACTION, HEARTBEAT,
TRANSACTION_EVENT) remain in switch for version-specific logic.

Adding a new command now requires 1 line in the registry instead of
a 5-line case block.
