Fix a11y contrast and harden flaky E2E tests

- Darken `--color-accent-text` from 40% to 55% black mix for WCAG AA compliance
- Add `opacity: 1` to search input placeholders to prevent browser dimming
- Replace fixed sleep with polling in file-watching duplicate check test
- Increase `waitForDialogsToClose` timeout to 30s for MTP conflict tests
- Make `waitForDialogsToClose` accept a configurable timeout parameter
