feat(jobs): due-date awareness — DueBadge + dashboard 'Geciken İşler' widget

dueDate was sitting on every job but the UI never warned anyone about
it. Added a small badge primitive and surfaced it everywhere a job is
listed plus a dedicated dashboard card.

  - lib/appwrite/due-date.ts: dueState() buckets a job into overdue /
    today / soon (1-3 days) / future / none, with delivered + cancelled
    jobs always resolving to none. dueLabel() returns the Turkish text.
  - components/due-badge.tsx: renders nothing for future/none, a
    secondary badge for today/soon, a destructive badge for overdue.
    Drop-in (job, className).
  - JobsTable (inbound + outbound): new 'Termin' column shows the date
    and the DueBadge stacked. Sorting still on createdAt for now —
    explicit ordering by dueDate will come with the filter task.
  - Job detail header: badge stack now has the DueBadge before the
    status pill so a glance at the page shows whether the case is
    behind schedule.
  - Dashboard: getDashboardData fetches up to 10 overdue jobs in
    parallel (lessThan('dueDate', now), excluding delivered/cancelled).
    Added a destructive-tinted 'Geciken İşler' card above the rest of
    the widgets when the list is non-empty, with quick links into each
    job's detail page.
