UI Phase 2: cosmetic leftovers — compact Profile photo card, fit Users table

- Profile Photo card: replace the tall centered avatar+buttons stack with a
  compact horizontal row (avatar left, caption + Upload/Camera buttons right),
  roughly halving the card height and reclaiming the dead vertical space.
- TasQColumn gains an optional `minWidth`; the adaptive table now sums per-column
  minimums instead of a flat 200 px each. User Management sets narrow widths on
  its short columns (Role/Offices/Status/Last active) so all six columns fit at
  desktop width without the horizontal scroll that was clipping the Status
  column. Other tables keep the 200 px default (unchanged).

Verified: flutter analyze lib clean; flutter build web green; visual QA
(Profile, User Management) in dark.
