fix(ux): pass-2 audit fixes — admin grouping, Duplicates entry, header tooltips

Three small but high-leverage fixes from the second audit pass on main:

Admin index (src/app/(dashboard)/[portSlug]/admin/page.tsx):
  - Grouped 21 sections into 7 categories: Access, Configuration, Content,
    Data Quality, Operations, Tenancy, Integrations. Each group has a
    one-line description so first-time admins can orient themselves
    without reading every card.
  - Added the missing Duplicates entry (links to /admin/duplicates from
    the dedup-migration work) under Data Quality.

More sheet (mobile bottom-drawer nav):
  - "Email" -> "Inbox". The page that opens is an email-inbox surface
    (Inbox + Accounts tabs), not a generic email composer. The previous
    label was ambiguous.

Interest detail header (Won / Lost outcome buttons):
  - Added title="Mark as won" / "Close as lost" so the icon-only buttons
    on mobile have a tooltip on long-press / desktop hover.
  - Tightened mobile padding (px-2 vs px-2.5) so the full-text desktop
    labels still fit on sm+ without re-introducing a regression where a
    visible mobile "Won"/"Lost" inline label crowded the right cluster
    enough to push Email/Call/WhatsApp action chips into a vertical
    stack.

Verification: 0 tsc errors, 926/926 vitest passing, lint clean.
