[chore]: Store Refactor

[jsanmigimeno]

Changes summary:

• The Store is now not chainId dependent. Wormhole engine does not need to load a store per chain anymore.
• Fixed AMBMessages/AMBProofs of the ack messages overwriting those of the delivery messages.
• The toIncentivesAddress is now saved to the AMBMessage type (no need for a separate registerDestinationAddress call). Persister also updated. Having a standalone function increased the likelihood of missing its implementation (e.g. on the LZ collector)
• Wormhole recovery worker now also recovers the transaction block hash and number (required by the new Store data types)
• The way the events are stored has been streamlined. The Bounty structure has been overhauled.
  • Remove unused ‘finalised’ field
  • Fix the unused ‘status’ field (the field was not being updated on message delivery/bounty claimed)
• Fixed how the 'amb messages by transaction hash' logic works (prevent data loss)
• Generalised the way in which custom collectors can save data to Redis.
