Cardano Updates

**Context** 
When using Mithril on mainnet and the node is fully synced, batches of
~200 blocks are written efficiently.

When the node is syncing without mithril, yaci-store processes blocks
sequentially, reducing sync performance.
In docker-compose setup, Yaci Store currently starts before the Cardano
node has fully synced to the tip. This can lead to sync inefficiencies
or unpredictable behaviour.

The unpredictable behavior is not related to data consistency, as long
as blocks already synced by the indexer are not reprocessed. However,
during node sync, the chain tip keeps moving, causing yaci-store to
switch between sequential and parallel modes, resulting in inconsistent
performance.


**Tests to Do**

- [ ] 1. sync test wtih SYNC=true, MITHRIL=true
        ***Expected behaviour***
        - [ ] Indexer should fully sync without being stuck
- [ ] DB, indexer and API should should start once the node is at the
tip

- [ ] 2. sync test with SYNC=true, MITHRIL=false
        ***Expected behaviour***
        - [ ] Indexer should fully sync without being stuck
- [ ] DB, indexer and API should should start once the node is at the
tip

- [ ] 3. sync test with SYNC=false, MITHRIL=true
      ***Expected behaviour***
      - [ ] Indexer should fully sync without being stuck
      - [ ] DB, indexer and API should would start together


- [ ] 4. sync test with SYNC=false, MITHRIL=false
        ***Expected behaviour***
        - [ ] Indexer should be stuck
        - [ ] DB, indexer and API should would start together

- [ ] Also test the offline mode set SYNC to false

- Introduced new tests for pool registration, certificate updates, governance voting, and retirement in `test_pool_operations.py`.
- Added environment variables for pool governance proposal ID and pool registration certificate in `conftest.py`.
- Updated `README.md` to include new pool operation scenarios and usage instructions.
- Implemented pool cold key signing functionality in `signing_handler.py`.
- Created new methods in `OperationBuilder` for building pool-related operations.
- Added a new environment configuration file `example.env` for easier setup of testing parameters.
