feat(admin/stops): add tabbed dashboard with calendar and locations views

Replace the table-only stops view with a three-tab 'Harvest Dispatch'
almanac dashboard.

- Calendar tab: month grid with stops as status-colored pins, day-detail
  side panel, prev/next/today nav, weekend tint, sunrise gradient on
  the current day.
- Locations tab: cards grouped by city+state with per-location stats
  (stops/active/upcoming), date range, next-stop ribbon, and inline
  expansion to list every stop at that location. Top of the tab shows
  a six-card almanac stats strip (Locations/Cities/Stops/Active/Upcoming/
  Drafts).
- List tab: condensed read-only list of all stops in date order.

Typography: load Fraunces (display), Manrope (body), and Fragment Mono
(mono) via next/font/google, wired into the Tailwind theme as
--font-display, --font-sans, --font-mono. Add typescript to devDeps
for tsc --noEmit in this environment.

Visual signature: cream parchment cards, forest green + clay accents,
Roman-numeral stat cells, paper-grain noise, binder-tab nav, route
number watermarks on location cards, harvest-pin SVG markers.

Verified with tsc --noEmit, eslint on the new files, and a 200 from
GET /admin/stops in the dev server.
