feat: stabilize Playwright tests after ActiveDid migration

- Fix dialog overlay handling across multiple test files
- Implement adaptive timeouts and retry logic for load resilience
- Add robust activity feed verification in gift recording tests
- Resolve Vue reactivity issues with proper type assertions
- Achieve 98% test success rate (88/90 tests passing across 3 runs)

The test suite now passes consistently under normal conditions with only
intermittent load-related timeouts remaining.
