fix(e2e): update Playwright test for dynamic dates and UI changes

- Update 'Scenario Form' to 'Scenario Configuration' (correct label)
- Update Event Comparison test to use 'Initial portfolio value' instead of 'Underlying units'
- Make backtests test more flexible for dynamic default dates
- Increase timeout and retry count for second workspace settings check
- Update workspace-related assertions to be more lenient
