UI: Cyber/IT design overhaul with semantic status tokens (Material 3)

Re-theme TasQ with a refined enterprise "Cyber/IT" identity on Material 3.
Functionality is unchanged — only color/shape tokens and a few state widgets.

Foundation:
- Hand-tuned light + dark ColorSchemes (deep-slate surfaces, azure/teal/violet
  accents), tightened 12-16dp shape language, flat hairline-outlined cards.
- New AppStatusColors theme extension (success/warning/danger/info/neutral,
  per-brightness) replacing scattered raw Colors.green/orange/red/grey so status
  color is consistent and legible in dark mode.
- New TechChip mono primitive; StatusPill.kind; M3Card hairline variants;
  tightened AppSurfaces radii.

Per-screen:
- Tokenized status colors + radii across dashboard, tickets, tasks, IT service
  requests, attendance, whereabouts, network map, reports charts, auth, and
  shared/admin screens. Added _ticketStatusKind/_taskStatusKind/_isrStatusKind
  mappers so status carries meaning consistently.
- Fixed white pie-slice borders for dark mode; dropped ad-hoc dialog radius
  overrides in favor of the theme default. Categorical palettes (leave-type
  icons, team color picker, distribution charts) intentionally preserved.

Verified: flutter analyze lib clean; flutter build web green; visual QA in
light and dark (dashboard, tickets, attendance).
