Updated rich-text editor

Updated rich-text editor

Upgraded the rich-text editor across Google SecOps, including the Cases Wall, Use Case Upload dialog, Report Template dialog, and Dashboard Editor widget.

Key changes include:

• Simplified typography: Choose font sizes using semantic options (Small, Normal, Large, Huge). Legacy font sizes on existing text are preserved. • Streamlined tables: You can insert or remove entire tables. Formatting inside table cells is no longer supported. • Toolbar cleanup: Removed the Cut, Copy, and Paste buttons from the toolbar. Standard OS keyboard shortcuts remain supported. • Visual alignment: Improved visual consistency between editor content during editing and after submission.
