basic volunteer dashboard

[jansm04]

implemented as per #184. Slightly modified the existing shift item in src/app/components/schedule so we can re use the code in the dashboard

Greptile Summary

This PR adds a volunteer dashboard with three widgets — upcoming shifts, shifts needing coverage, and a check-in countdown — and refactors ShiftItem to accept an optional onOpen callback so it can be reused outside the schedule page context.

• P1 — dashboard-checkin-widget.tsx lines 52–55: AttendanceStatus.excused is included in hasCheckedIn, so a volunteer who is excused (but never checked in) will incorrectly see the "Checked In!" success card. Only present and late should be treated as a real check-in.

Confidence Score: 4/5

Safe to merge after fixing the excused status logic in the check-in widget.

One P1 logic bug (excused treated as checked-in) should be resolved before merging; remaining findings are P2 style/UX issues that don't block the feature.

src/components/dashboard/dashboard-checkin-widget.tsx — incorrect hasCheckedIn condition.

Vulnerabilities

No security concerns identified. The check-in mutation correctly delegates authorization to the server-side tRPC procedure, and no sensitive data is exposed client-side.

Important Files Changed

Filename	Overview
src/components/dashboard/dashboard-checkin-widget.tsx	New check-in countdown widget; excused attendance status is incorrectly treated as checked-in, causing the success card to display for volunteers who are merely excused from the shift.
src/components/dashboard/dashboard-upcoming-shifts.tsx	New upcoming-shifts card using useShiftRange; now is captured once at mount so ended shifts won't be filtered out without a page reload; minor indentation inconsistency in the Link block.
src/components/dashboard/dashboard-coverage-shifts.tsx	New coverage-shifts card; coverage take/withdraw mutations and query integration look correct; stale now used as query from param (same pattern as upcoming-shifts).
src/components/schedule/shift-item.tsx	Refactored to accept optional onOpen prop; falls back gracefully to SchedulePageContext or a no-op, allowing reuse outside the schedule page without breaking existing callers.
src/components/schedule/schedule-page-context.tsx	Exports SchedulePageContext directly so shift-item.tsx can use useContext instead of the throwing useSchedulePage hook; no behavioural change for existing consumers.
src/app/(authorized)/page.tsx	Routes volunteers to the new VolunteerDashboard layout; non-volunteer roles still see the "under construction" empty state; missing trailing newline.

Stale now reference for shift filtering

now is captured once at mount and never updated, so upcomingShifts won't drop a shift that ends while the page is open. The same pattern exists in DashboardCoverageShifts. If the page stays open past a shift's end time, the ended shift will remain visible until a full reload.

Suggested change

	const now = useMemo(() => new Date(), []);
	const now = new Date();

Inconsistent indentation in Link block

The inner elements of the Link are indented with extra spaces relative to the surrounding code. The same pattern appears in dashboard-checkin-widget.tsx.

Suggested change

	<Link
	href="/schedule"
	className="flex items-center gap-1"
	>
	<CardTitle className="text-base font-semibold">My Upcoming Shifts</CardTitle>
	<ChevronRight className="size-4 text-muted-foreground" />
	</Link>
	<Link href="/schedule" className="flex items-center gap-1">
	<CardTitle className="text-base font-semibold">My Upcoming Shifts</CardTitle>
	<ChevronRight className="size-4 text-muted-foreground" />
	</Link>

Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

Missing newline at end of file

page.tsx, shift-item.tsx, and dashboard-upcoming-shifts.tsx are all missing a trailing newline. Most linters and Git tools expect files to end with a newline.
