@fullcalendar/core 7.1.1 on Node.js Yarn

FEATURE: @fullcalendar/mui supports MUI v9 (in addition to v7). MUI skipped v8
FEATURE: Resource views, render hooks receive info.resource, the resource of the column/lane being rendered into (#4926)
- Event hooks: eventContent, eventClass, eventDidMount, etc, including the *EventTimeClass/*EventTitleClass variants and backgroundEvent* hooks. An event with multiple resources renders once per resource, each with its own info.resource. A dragged event's mirror receives the resource it's being dragged over
- +more link hooks: moreLinkContent, moreLinkClass, moreLinkDidMount, etc
- +more popover hooks: the popover's events, as well as dayHeader* and dayCell* hooks where info.inPopover
- Not populated in non-resource views. Compare info.resource.id, not the object itself, which is not guaranteed to be the same reference across columns
- New EventTextInfo type, for the arg of *EventTimeClass/*EventTitleClass hooks, which now also receive timeText
FIX: Resource TimeGrid/DayGrid, preserve dates with no resources when filterResourcesWithEvents is enabled (#8099)
- With datesAboveResources, such a date renders a single non-interactive column with no resource. Day cell/lane hooks for it receive no info.resource, so guard for it:
```
dayLaneClass: (info) => info.resource ? `lane-${info.resource.id}` : ''
```
FIX: React 19, "Received an empty string for a boolean attribute inert" warning with dayMaxEvents/eventMaxStack. The offscreen +more link used for measurement also wasn't made inert, so it could receive keyboard focus (#8114)
FIX: Resource TimeGrid/DayGrid, spanning header cells sometimes misaligned with body columns by 1px
FIX: Resource Timeline view, with virtualization, leading header cells and slots missing when the timeline is wide enough to not need horizontal scrolling (#8093)
FIX: Resource Timeline view, with virtualization, rows blank until scrolled after removing and re-adding resources within batchRendering, such as for a filter
FIX: Resource Timeline view, with virtualization, first resource row hidden or clipped under the header after removing and re-adding resources, such as for a filter, while scrolled at or near the top
FIX: Timeline views, printing a timeline that's wide enough to not need horizontal scrolling clips the leading slots, as if scrolled to scrollTime
