Add logging at each stage:
- Context manager entry/exit
- submit_vote() method entry
- Validator selection
- HTTP request details
- Response handling
This will help identify exactly where the vote submission is failing.

Problem: Votes were being rejected by validators with 'Invalid data format'
error because the transaction data wasn't in the correct format.
Root cause: The validator's eth_sendTransaction endpoint expects the 'data'
field to be:
1. A hex string prefixed with '0x'
2. The hex-encoded JSON of a Transaction object containing:
- voter_id
- election_id
- encrypted_vote
- ballot_hash
- timestamp
Solution:
- Update BlockchainClient.submit_vote() to properly encode transaction data
as JSON, then hex-encode it with 0x prefix
- Add ballot_hash parameter to submit_vote() method
- Update both call sites in votes.py to pass ballot_hash
- Generate ballot_hash if not provided for safety
This ensures votes are now properly formatted and accepted by validators,
allowing them to be submitted to the blockchain instead of falling back to
local blockchain.

validator-2 was incorrectly configured to use port 8001 (should be 8002)
validator-3 was incorrectly configured to use port 8001 (should be 8003)
This was causing validator-2 and validator-3 to be unreachable from the
backend container, resulting in votes being submitted to the local fallback
blockchain instead of the PoA validators.

The backend container needs to reach validators using their Docker service names
(validator-1, validator-2, validator-3) instead of localhost:PORT.
This fixes the 'validators unreachable' warning on backend startup.
