fix: persist regime to DB in shared _build_state, deduplicate save logic

- _build_market_state (CLI) now saves regime_history automatically
- _build_state (web) now saves regime_history automatically
- Remove duplicate regime save from cmd_score
- Remove unused imports (timedelta, get_connection)
- Fix: web dashboard never updated regime_history table
