Adds manual transaction processing feature

Implements functionality to manually process specific Lamassu transactions by ID, bypassing dispense checks.

This allows administrators to handle transactions that may have failed due to dispense issues or were settled manually outside of the automated process.

The feature includes a new UI dialog for entering the transaction ID and an API endpoint to fetch and process the transaction, crediting wallets and distributing funds according to the DCA configuration.
