Open a profile's followers and following from its counts

[simonhamp]

Tapping "N followers" or "N following" on a profile now opens the list of those people, as on the web.

What changed

• New Connections screen at {tab}/users/{username}/followers and /following, pushed in the tab you tapped from. Titled "@ada's followers" or "@ada's following".
• Each row copies the web's connections page: avatar ringed in their lane, name, handle, up to two lines of bio, and Follow or Following. It adds the app's "Follows you" badge where it applies. Your own row has no button. Tapping a row opens their profile.
• Follow and Following flip straight away and go back if devnull refuses, like the profile's button. Follow wears your lane colour, as the other main buttons do since Wear your lane colour on the main buttons, and make full-width buttons large #8, and is in the lane buttons test.
• On your own Following, unfollowing keeps the row as Follow until the list refreshes, as the web does, so a mistaken tap is one tap to undo. The web has no way to remove one of your followers, so neither does the app.
• On your own Followers the "Follows you" badge is left off, because every row would have it.
• Follow and Following sit in a 96pt slot so the button doesn't change width when it flips. A width class on the button itself does nothing, since EDGE sizes buttons to their label.
• Load more on scroll, pull to refresh, and the web's empty states ("fatal: no followers yet", "Nobody is following @ada yet."). Across a block it shows the same message as the profile.
• Lists are kept in the ResponseCache like the other screens: the first page shows at once, then refreshes behind it. A refreshed first page with no more after it replaces the list, so people who left go.

Cache changes reviewers should look at

• ResponseCache::followChanged used to count a follow on your own profile only when the other person's profile was kept. Following someone from a list whose profile you never opened left your Following count wrong until the next refresh. Now a missing profile counts as a change.
• A follow also sets is_followed on that person in every kept follower list, following list and notification group, so going back to any of them shows the new state at once.
• Connections has a listPath() helper, not path(). A path() method on the class overrides OpensInTab's private static path() and quietly breaks openInTab.

API

Needs the followers and following endpoints from simonhamp/devnull.com#2, which is stacked on nunomaduro/dev-null.sh#130.

Verification

php artisan test on the rebased branch: 728 passed. The 2 deprecations come from Activity.php and were there before this branch.

On an iPhone 17 Pro simulator (iOS 27), signed in as local_dev against a local copy of the API branch, with a test user fl_ada who has 36 followers (since removed):

Your profile	Your following	Their followers

Their following	Empty	Dark

After rebasing onto main (#9, #3, #7, #8, #4, #5) I checked it again on a fresh simulator, this time with taps: signed in through Sign in with GitHub, opened my Following from the count, unfollowed fl_ada (the row stays, Follow comes back in my lane colour at the same width), went back and the count had dropped from 2 to 1. Then I opened my Followers, a row (dking's profile), their followers, followed fl_ada again, opened fl_ada and their 36 followers, scrolled to the end (load more fetched the second page), followed Follower 1 there, and went back to find 3 following on my profile. Pull to refresh on my Following kept the list right.

Recordings: unfollow and the count, browsing, following and load more.
