refactor: update database schema and fix chain_id handling across components

- Add new Transaction fields: nonce, value, fee, status, timestamp, tx_metadata
- Add block_metadata field to Block model
- Remove account_type and metadata fields from Account creation
- Simplify contract deployment transaction structure
- Fix chain_id hardcoding in PoA proposer and RPC router
- Update config to use /opt/aitbc/.env path with extra="ignore"
- Switch from starlette.broadcast to broadcaster module
- Update CLI
