Fix multiple UI/UX issues and invite token migration

Fixes:
- Round edit: Add cache invalidation for voting dates
- Criteria weights: Replace number input with visual slider
- Member invite: Per-member expertise tags with suggestions
  - Tags now added per member, not globally
  - Comma key support for quick tag entry
  - Suggested tags based on ocean/business expertise
- Accept-invite: Add Suspense boundary for useSearchParams
- Add missing inviteToken columns migration

The invite token columns were accidentally skipped in prototype1
migration. This adds them with IF NOT EXISTS checks.
