refactor(ui): the settings family migrates; two colour bugs and a dead class

SettingsView and UserManagementView had near-identical button vocabularies —
btn-delete, btn-cancel-delete, btn-confirm-delete, btn-toggle/-open/-close —
defined separately in each. Parallel duplication (#2278's shape), and it had
already diverged twice:

- .btn-confirm-delete used --color-danger in UserManagement and
  --color-action-destructive in Settings. Those are different colours on
  purpose: the house style keeps error (something went wrong) distinct from
  destructive (something is about to). A delete confirmation is destructive.
  UserManagement was showing the error colour for a button nothing had failed
  in yet.

- .btn-remove-slot's hover reached for --color-danger for the same reason, and
  is the same correction. It turned out to be dead anyway — style rules only,
  no template reference anywhere in the app — so it is gone.

.btn-danger-outline was defined TWICE inside SettingsView, at 0.4rem 0.9rem and
0.45rem 1rem. One file, one class, two geometries, ~1200 lines apart. That is
the clearest single argument for this whole task that I have found: the drift
does not need two files, only enough distance that nobody sees both at once.

The registration toggle keeps .btn-toggle-close, and only that. It is bound
dynamically (:class="registrationOpen ? … : …"), so a name-based scan reads it
as unused — checked before deleting. .btn-toggle-open went, because btn-primary
now says the same thing; the close state stays because it must NOT read as the
primary action it sits on.
