rollbackDustActions

Rolls back dust actions (unlocks coins after transaction failure).

When to call:

• Transaction submission failed

• Transaction was rejected by blockchain

• User cancelled transaction

Current Implementation: No-op for MVP. DustLocalState manages UTXO state internally. When dust spends fail, the state is not saved, so UTXOs remain available.

Future Enhancement: Track PENDING/AVAILABLE states in database for UI display.
