DS-030: Standardize Skeleton variants

[IbrahimIjai]

Complexity: Trivial
Primary files: packages/ui/src/components/skeleton.tsx, apps/web/src/shared/components/skeleton

Consolidate duplicate skeletons and add text, avatar, control, card, and table-row
presets.

Acceptance criteria

• Feature code imports skeletons from @workspace/ui.
• Presets use the radius and motion tokens.
• Reduced-motion users see a static treatment.
• Duplicate implementation is removed after call-site migration.
