feat: (finally) add user profiles

[lewislarsen]

I noticed earlier that the Roadmap had a placeholder profile page that was (3!) years old, so my project tonight was to try to put something there instead. 😉

Some highlights of this PR include:

• Added a button on the /profile page to take you to your public profile.
• Added public profile links to the item card and the comment card.
• Added a link to public profiles on the Activity table.
• Truncation for long content on the public profile page!
• New language file for public profiles, splitting it up from general.php.
• Only shows content the authenticated user can see, if an item is private for example, it won't be shown.

I did my best to match the design of the activity feed on the item page.

It is extremely good to hear from you Lewis! 🔥

Awesome addition, I have indeed never taken the time to properly create a public profile page, but this covers it completely.

Thanks! 🥰
