Only use d/f switching / dynamic space direction for d/f (#8786)

The d/f switching / dynamic space direction got wonky since rotating the
viewports is allowed (see #8614). It impacted the moving via alt+mouse
to move in wrong directions. Therefore, this PR disables the dynamic
space direction to be only used / applied when using the acutal d/f
short cuts. The other possibilities should not be affected by d/f
switching anymore.

### URL of deployed dev instance (used for testing):
- https://___.webknossos.xyz

### Steps to test:
- do the same on master as well as on this branch
- Open an annotation.
- Brush in z layer X
- Brush in z layer x-5 or so (should be smaller than before, to cause
the "flipping")
- Turn on d/f switching in the left settings drawer
- move via alt + mouse. On master this should not move as expected. On
this branch, this should be fixed


### Issues:
- verbally reported bug

------
(Please delete unneeded items, merge only when none are left open)
- [x] Added changelog entry (create a `$PR_NUMBER.md` file in
`unreleased_changes` or use `./tools/create-changelog-entry.py`)
