Confirming the PDF's Import Options placed it without append, so in a batch such as [a.png, b.png, multi.pdf] it replaced the images already in the cursor. The dialog now carries append, on both the native and the delivered-file paths. A single multi-page PDF still replaces what the cursor holds.
Review fix for #2309: set_active, add_document and close_document emptied the place cursor but
kept the placeGun tool, so the next canvas click failed with 'nothing loaded in the place
cursor'. One helper, Session::unload_place_cursor, empties the cursor and its queue and goes back
to the Selection tool when the place cursor's tool is active; validate_place_cursor uses it too.
Test: changing_documents_unloads_the_place_cursor_and_its_tool.

The place cursor's grid preview fell back to the raw drag rectangle when the
cells had no positive size, while the release still sent `place.grid`, which
rejected the area. Both now use the same cell calculation (`grid_cells`), and
a grid with no room for its cells shows and places the single proportional
frame of an ordinary drag.
Split out of #2073. Port of #1307's drops and #1666.
- Several images dropped together load the place cursor in the order they
came, each run of them where it comes among the other files, after the
images it already holds; click to place them one by one.
- One image dropped off a frame that takes it loads the place cursor instead
of being placed at once; on such a frame it still fills it.
- A drop is handled in its order, each file at its own pointer, and a dialog
(a multi-page PDF's Import Options, an alert) cancels the rest.
- On the web, files dropped together are read as one batch (none if one
can't be read), and a single dropped image loads the place cursor.
Split out of #2073. Port of #1307, #1392 (grid) and #1432 (thumbnail and count).
- File › Place takes several files; images load the place cursor in the
order chosen (`place.load` `files`, `append`), after the ones it holds.
A multi-page PDF or an alert stops the batch, and a file that can't be
placed returns its error to `app.placeDialog`.
- Each click places the next image; arrow keys while dragging lay out a
grid (`place.grid`) and are handled even at a limit; Escape unloads the
rest (`place.cancel`). Undo of a loaded image's asset cancels the queue.
- The cursor shows how many images are loaded.
- On the web, Place picks several files and the inbox loads consecutive
images for the same document as one batch.
