fix(dashboard): update sync card after completion + use Bucharest timezone

Sync card was showing previous run data after sync completed because the
last_run query excluded the current run_id even after it finished. Now only
excludes during active running state.

All datetime.now() and SQLite datetime('now') replaced with Europe/Bucharest
timezone to fix times displayed 2 hours behind (was using UTC).
