Closes #8119, follow-up of #8234#8234 "only" fixed the case when a new wiki setting was applied.
However it lacked 2 aspects:
- fixing the already corrupted unit permission in the database (required a migration)
- fixing the API route
Both aspects should now be covered.
Additionally, I commented out the unused `UnitAccessMode` and indicated that they are only used for the wiki-unit (hopefully saving some time to future code-readers).
### Testing
- go to a commit before #8234 (e.g. 285f66b782)
- create 3 repositories
- save the wiki settings of the second, without any change
- set the wiki of the third to be globally writable
- verify the `default_permissions` column in the database, of the unit `5`: 0, 2, 3
- stop Forgejo, switch to this PR and start Forgejo
- verify that the logs writes `Migration[35]: Fix wiki unit default permission`
- verify the `default_permissions` column in the database, of the unit `5`: 0, 0, 3

- [x] I did not document these changes and I do not expect someone else to do it.
- [x] I do not want this change to show in the release notes.
