feat(admin): fix admin shell theme tokens, declutter dashboard, add active-page nav highlight

Admin shell used hardcoded zinc-* classes instead of semantic design tokens and
a redundant "PawFeed Admin" kicker label. Dashboard was a wall of 12 identically
weighted stat cards with no hierarchy. Sidebar/mobile nav gave no indication of
the current page.

- layout.tsx/AdminMobileNav.tsx/GranularityToggle.tsx/TimeSeriesChart.tsx: replace
  zinc-* with bg-background/text-foreground/border-border etc., force dark via
  the `dark` class so the admin surface stays permanently dark regardless of
  site-wide theme toggle
- New AdminSidebarNav.tsx: highlights the current page (desktop sidebar)
- AdminMobileNav.tsx: same active-state logic for the mobile drawer, topbar
  shows the current page label instead of a static title
- page.tsx: replace the 12-card stat grid with 2 AttentionStat tiles (reports,
  pending verifications — color means "act on this") plus a flat Overview list,
  and convert the 5 chart containers to the shared Card component
