Add time clock feature with MCP access

- New beenvoice_time_entry DB table with migration (startedAt/endedAt, hours, rate, clientId)
- tRPC router with clockIn, clockOut, getRunning, getAll, getSummary, create, update, delete
- Dashboard page at /dashboard/time-clock with live elapsed timer, entry list, and manual entry form
- 5 MCP tools: time_clock_in, time_clock_out, time_get_running, time_entries_list, time_entries_create
- Sidebar navigation entry

Timer state is stored in PostgreSQL (endedAt IS NULL = running), suitable for serverless/Coolify deployment.
