FN-6149: tokenize bare hex colors in dashboard CSS

Replace hard-coded dashboard hex colors with semantic tokens and guard the cleanup with regression coverage.

- swap bare hex colors in ScriptsModal.css for semantic custom properties
- swap bare hex colors in SettingsSyncLog.css for semantic custom properties
- add regression coverage for bare hex literals outside var() fallbacks in audited dashboard CSS
- add a patch changeset for @runfusion/fusion
