fix(frontend): auto-completed on finish time, dashboard links, list/calendar UX

- Set status to completed when finish time parses (input + submit)
- Dashboard: last personal record by recent date+time; links on top 3 cards
- Hover scale+shadow on all dashboard-card; linked card padding via BEM
- Race list: full row links to race detail; same hover as before
- Calendar year grid: 3 columns, 2 on tablet, 1 on narrow
- Version 0.4.1
