Summary by cubic

Allow clearing the Trust Portal primary brand color to reset branding to the default theme. Updates validation and autosave so empty input persists as a reset and invalid hex values are ignored.

• Bug Fixes
  • Treat empty input as a reset: normalize returns null for empty, undefined for invalid; valid hex is uppercased.
  • Autosave/blur skip invalid values and persist resets by sending primaryColor: '' to the settings API; callbacks receive null.
  • Input shows blank when unset instead of forcing a default color.
  • Added a test to verify reset behavior and navigation refresh.
