Self-follow check used get_attribute(:follower_id) which is nil at
validation time because relate_actor runs after validations in Ash.
Fixed to use context.actor.id directly.
Added 9 tests covering: follow, follow idempotency, self-follow
prevention, guest restriction, unfollow, unfollow noop,
guest unfollow, follower/following counts, and am_i_following.

- unlike noop now reloads tweet from DB (same fix as like noop from prev loop)
- decrement_likes uses GREATEST(likes - 1, 0) to prevent negative counts
- add fix_plan.md to track remaining work

- Add authorize?: false to user_fixture so register_with_password
bypasses policy check in test context
- Add require Ash.Query so Ash.Query.filter macro works in count_likes
- Replace nonexistent Ash.ForbiddenField.forbidden?/1 with match?/2
- Fix stale tweet struct in :like noop case by reloading from DB
