Expose license detection edit operations (incomplete, behind experimental).

• Support dual licensing in UI and possibly in search #5359
• Colors and the interactive feature is incomplete (clicking on the removed icon exposes the removed text segment - or a snippet of it).
• Note: the input from pana seems to be not consistent enough for this feature to be useful at this point, but I'd rather have it behind experimental, so that we can better find detection runs where the offsets or operations are off.

Note: pushed to staging.
