TSDK-790 Claim BTC [Backend - do not merge yet]

[mundacho]

Purpose

Once the tBTC are redeemed from the Topl side (during peg-in), we need to claim the BTC to the topl wallet. This requires:

• sending a transaction to the BTC network
• waiting for the transaction to be completed (using the monitoring)
• informing the user that the process has been completed

This PR is limited to the backend.

Approach

• We continue our refactoring to use a state machine to handle the states.
• We are not including yet the time locks

Testing

• Adapted integration tests.
• Unit tests of the state machine were added

Tickets

• TSDK-790 TSDK-804
