Cardano signatures are not produced on `testing-sanchonet` and `testing-mainnet`

[jpraynaud]

Why

Cardano transactions are not produced consistently on the testing-sanchonet and testing-mainnet. The problem is not occurring on the testing-preview network which is running the same code as testing-sanchonet.

What

Investigate and fix the problem which prevent consistent signing.

How

• [x] Investigate the problem on the signature process
  • [x] testing-sanchonet: parse problem with some blocks
  • [x] Activate GitHub environment variable AGGREGATOR_ALLOW_UNPARSABLE_BLOCK to true
  • [x] File a bug on pallas repository
  • [x] testing-mainnet:
  • [x] timeout when importing some immutable files
• [x] Fix the signature process
  • [x] testing-sanchonet:
  • [x] Apply patch
  • [x] Rollback GitHub environment variable AGGREGATOR_ALLOW_UNPARSABLE_BLOCK to false
  • [x] Reset Cardano transactions stores of aggregator and signers
  • [x] testing-mainnet:
  • [x] Apply patch for timeout

I commented on the issue https://github.com/txpipe/pallas/issues/410#issuecomment-2114741073 with the problem that we have noticed with blocks parsing with pallas.
