The POST /api/votes endpoint (used by frontend) was recording votes
in the database but NOT submitting them to the PoA blockchain. This
caused votes to appear in database but not on the blockchain.
Changes:
- Add vote submission to PoA validators in the simple endpoint
- Add fallback to local blockchain if PoA validators unreachable
- Include blockchain status in API response
- Use ballot hash as vote data for blockchain submission
This ensures votes are now submitted to the PoA blockchain when the
frontend votes, and users can see their votes on the blockchain.
