Step 2 of #9337: the course-event features the legacy agenda still had are now in the Vue agenda, and the legacy agenda page redirects to it.

Changes

• Visibility fix. No layer filtered resource_links.user, so a course event sent to one user (for example, one created with the legacy agenda.php) was visible to the whole course, and the personal agenda listed events sent to other users and to other groups. A learner now sees the events of the whole course, of their groups, and the events sent to them, as in Agenda::getCourseEvents(). Teachers see all of them. Outside a group, GroupContextQueryExtension no longer hides the events of the learner's groups (only for CCalendarEvent).
• Recipient validation. AgendaHelper::canAddLinks() rejects a uid that is not subscribed to the course (or to the course in the session) and a gid of another course.
• Send to. Teachers choose users and groups when they create or edit a course event. There is a new GET /api/calendar/course-recipients endpoint (teachers only). courseRecipients in the PUT replaces the links of the event in the current course. ResourceListener keeps the gid of a single-link calendar event outside a group context; the CREATE voter validates it first.
• Filter. recipient=USER:<id>|GROUP:<id> lists the events sent to one user or group. It only has an effect for course editors. The selector is shown in the month view and in the list view.
• Redirects. calendar/agenda_js.php redirects by type (admin/platform → ?type=global). my_space/calendar_plan.php, which was already broken on master, redirects to the personal agenda, and its links were removed. inc/ajax/agenda.ajax.php and agenda/month.html.twig were deleted (both are in UPDATE-METADATA.json).

Tests

• tests/CoreBundle/Api/CCalendarEventRecipientApiTest.php: 11 tests covering visibility per role, recipient validation, editing recipients, the filter and the recipient endpoint. The visibility and validation tests fail without the fix.
• Playwright: calendarCourseRecipients.feature (new) and agendaLegacyRedirects.feature (extended).
• Documentation: 3.x/en/teacher-guide/additional-tools/agenda.md in the docs repository (all branch).

Out of scope

• CCalendarEventVoter lets only the creator edit an event, so another teacher of the course cannot edit it.
• A learner with allow_user_edit_agenda can send links with uid/gid through the API. The legacy form did not show the selector to learners.
