[Proxy colony M2] feat: handle when a proxy colony's funds have been claimed

[bassgeta]

Specification

Story

As a colony with a proxy colony, I want to know when incoming funds on that proxy colony have been claimed.

Description

After #3459 is done, we need to implement a simple UI for testing purposes which will display all incoming funds with buttons to claim them. We need to call the claimTokens contract with that chainId and tokenAddress and start the process. (TBD check which exact contracts to call).
When the funds get claimed, a proxy colony emits an DomainFundsClaimed event, which the parent colony receives.
We then need to handle that in the parent chain's block ingestor and set the claimed flag to true and update the balances.

Implementation

This issue is complete when...

• We can claim incoming funds for a specific token
• The claim transaction goes through, the main colony's block ingestor will handle the event and update the DB
