Closes#17089
### 1. Can't reopen record after having navigated to its show page
After opening a record in the show page from the command menu and going
back to the index, clicking the same record again did nothing. The
command menu navigation stack was not cleared when opening in the show
page, so the "already open" check skipped reopening. We now clear the
command menu navigation stack before navigating to the show page (in
`RecordShowRightDrawerOpenRecordButton`), so the same record can be
reopened from the index.
### 2. Row doesn't highlight when opening command menu after return from
show page
After returning from the record show page to the index, the first row
click opened the command menu but the row did not highlight. The "side
panel close" event was emitted not only when the panel actually closed,
but also when opening the command menu (cleanup ran with
`isCommandMenuClosing` and always emitted the event). Listeners like
`RecordTableDeactivateRecordTableRowEffect` then deactivated the row. We
now emit the side panel close event only when the close animation
actually completes (`CommandMenuSidePanelForDesktop`), and skip emitting
it when cleanup is run from the open path (`useNavigateCommandMenu`
passes `emitSidePanelCloseEvent: false`). The table still deactivates
the row when the user closes the panel, but no longer when they open the
command menu by clicking a row.
