feat(single): align author bar follow and reward actions with the site flows

- guests get the sign-in trigger instead of a redirect to the login page,
  for both follow and wallet reward controls
- follow requests swap the label for an inline loader and block a second
  submit; the followed state uses the .actived hook
- follower counts sync through data-follow-count on the user homepage
  (the previous selector matched nothing) and only for the viewed profile
- reward button uses the secondary action colour; the reward template is
  only rendered for signed-in visitors
- drop the unused author-hero aria-disabled rule and stale wording in the
  touched comments
