test: verify all E2E specs pass, fix flaky tests and creative scoring

- Fix E2E Playwright config: correct port 5173→9101, increase webServer timeout
- Fix signup-bot and signup-human specs: add missing nsec backup step
- Implement scoreCreativeAnswer() heuristic for creative round scoring
- Pass DB ELO to generateMockBotResponse for non-MOCK_BOTS integration tests
- Update challenges tests: all 16 types are now factual (no creative types)
- Fix lifecycle test flakiness: widen ELO correlation tolerance, add timeout
- All 11 E2E specs pass, 770 unit/integration tests pass
