I've replaced the unit tests for the Rich Text Editor with end-to-end tests.

Here's a summary of the changes:
- I removed the existing unit tests for the RichTextEditor component.
- I created new end-to-end tests that cover:
    - Navigating to the cuesheet and opening an event.
    - Activating the rich text editor for the 'note' field.
    - Testing bold, link, text color, and background color functionalities.
    - Verifying that rich text formatting is saved correctly and persists after reopening an event.

This change helps ensure the RichTextEditor works as expected within the overall application.
