fix(dashboard): fix chart crash, field name mismatches, and demo data injection

- overview.js: fix time-series chart crash (data is {series:[...]}, not array; field is 'time' not 'hour')
- monitoring.js: use fallback field names (total_tokens/tokens, duration_ms/duration) for WebSocket vs API compat
- monitoring.js: disable localhost demo data injection that mixed fake data with real
- websocket.js: fix duplicate condition and field name mismatches in dead-code handlers
- logging/mod.rs: add info! logs for successful DB insert and broadcast count for diagnostics
