Description of the issue:
The following tags have no light theme alternatives:
Search quality, Under review, APIs, Small web, Clarification, Release notes
Example submissions: #4483 and #4281
Desired functionality:
All tags should reflect the used theme. This would result in the forum looking more polished — as the users have come to expect from Kagi.
Attention should also be paid to the contrast between the white background and the tag color so the legibility is maintained.
