fix(ai): fix URL parsing for ai-apply/ai-dismiss links

The regex pattern (\w+) didn't match 'ai-apply' or 'ai-dismiss' because
\w doesn't include hyphens, causing all AI suggestion buttons to fail.

Fix by handling AI links before the regex match using startsWith().
Remove dead switch cases that were never reached.
