fix(pres_mgmt): presenter QR follows session QR global-default pattern

show__presenter_qr (admin) is meant to be the global default for everyone,
signed in or not. show_content__presenter_qr is a trusted-staff-only local
override for when the admin hasn't enabled it globally. Presenter QR was
still on the old logic requiring show_content__presenter_qr to also be
true even when the admin enabled it for everyone — non-trusted users
(presenters) have no way to set that flag, so QR never appeared for them.

- presenter_view.svelte: generation effect + display block now use
  show__presenter_qr || (trusted_access && show_content__presenter_qr),
  matching the session_view.svelte fix from earlier today
- presenter_page_menu.svelte: QR toggle was gated to administrator_access,
  hiding it from plain Trusted onsite staff; loosened to trusted_access
  and dropped the redundant `|| trusted_access` (now only shown when
  admin hasn't already enabled QR globally)
- ae_comp__events_menu_opts.svelte: both session and presenter QR toggles
  were visible to all authenticated_access users whenever admin had
  enabled QR globally, even though the toggle had no effect for them;
  now gated to trusted_access && !show__*_qr, matching session_page_menu.svelte

+- [x] **Presenter QR matched to session QR pattern (2026-06-16)** — `show__session_qr` /
+  `show__presenter_qr` are the admin-set **global default for everyone**, signed in or not.
+  `show_content__*_qr` is a **trusted-staff-only local override**, used when the admin has
+  NOT enabled QR globally. The session QR side already worked this way (fixed earlier today);
+  presenter QR was still on the old buggy logic requiring `show_content__presenter_qr` to be
+  true even when the admin had enabled it for everyone, which non-trusted users (presenters)
+  have no way to set. Fixed `presenter_view.svelte` (generation effect + display block) to
+  `show__presenter_qr || (trusted_access && show_content__presenter_qr)`. Also corrected two
+  toggle-button visibility bugs found along the way: `ae_comp__events_menu_opts.svelte` was
+  showing the QR toggle to all `authenticated_access` users (not just trusted) whenever the
+  admin had enabled QR globally, even though the toggle had no effect for them; and
+  `presenter_page_menu.svelte`'s QR toggle was gated to `administrator_access`, hiding it from
+  plain Trusted onsite staff entirely. Both now use the canonical pattern from
+  `session_page_menu.svelte`: `trusted_access && !show__*_qr`.
