feat: add clickable activity cards with comment anchor links to profile tab

Add `url` field to profile activity items so post cards link to `/posts/{slug}` and comment cards link to the parent post with a `#comment-{uid}` anchor, matching notification click behavior. Include the shared `_card_link.html` overlay in the template, fix XP bar rendering for missing `xp` key, and add API + e2e tests verifying the link structure and navigation.
