Bonsai: persist link IFC query across reload

Store the selector query used at Link IFC time on the Link
PropertyGroup, restore it from the sidecar cache JSON on host
IFC reopen, and forward it through LoadLink and ReloadLink so
subsequent reloads replay the original filter instead of loading
every element. ReloadLink now opens a small dialog pre-populated
with the current query, allowing the user to edit it in place
without unlink-and-relink.

Also swap TestCalculateLinkMatrix off NamedTemporaryFile(delete=True)
which held an exclusive Windows handle and blocked the
code-under-test from reopening the sidecar path.

Closes #8219
