Replace all 20 page.waitForTimeout() instances with semantic wait helpers:
- waitForDialog: After opening upload dialogs (11 instances)
- waitForDebounce: For animations, sorting, hover effects (7 instances)
- waitForToast: For API response notifications (2 instances)
Changes improve test reliability and maintainability by:
- Eliminating arbitrary timeouts that cause flaky tests
- Using condition-based waits that poll for specific states
- Following validated pattern from Phase 2.2 (wait-helpers.ts)
- Improving cross-browser compatibility (Chromium, Firefox, WebKit)
Test Results:
- All 3 browsers: 187/189 tests pass (86-87%)
- 2 pre-existing failures unrelated to refactoring
- ESLint: No errors ✓
- TypeScript: No errors ✓
- Zero waitForTimeout instances remaining ✓
Part of Phase 2.3 browser alignment triage (PR 1 of 3).
