Rehome 32 tests/ui/issues/ tests to other subdirectories under tests/ui/

[Oneirical]

#143902 divided into smaller, easier to review chunks.

Part of #133895

Methodology:

1. Refer to the previously written tests/ui/SUMMARY.md
2. Find an appropriate category for the test, using the original issue thread and the test contents.
3. Add the issue URL at the bottom (not at the top, as that would mess up stderr line numbers)
4. Rename the tests to make their purpose clearer

Inspired by the methodology that @Kivooeo was using.
