fix(dashboard): resolve Asma tester-reported UI issues

- 3.1 currency: replace hardcoded $ with AED <Money/> in item & job-card price cells
- 5.1 calendar: /calendars now renders the month calendar (was redirect to list)
- 7.2 nav: remove dead Time Clocks / Time Sheets links (no routes, 404)
- 5.4 check-in: enforce required department at schema level
- 5.6 payments received: add invoice picker so the invoice is marked Paid
- 5.2 share link: forward ws workspace param from the public inspection page
