feat(ui): open Database-mode nests from a larger saved-nest browser

File > Open in Database mode now shows a resizable browser instead of
the small list dialog. The upper Nests grid keeps the server-side
search, sort and paging (row numbers count through the filtered list;
the title shows the server and the range). Below it, Details tabs list
the highlighted nest's plates and drawings, read from its archive after
the highlight rests for 250 ms; moving back to a nest already shown
reuses its result, and a missing archive is reported in the details
line.

Enter opens the highlighted nest (in the Find box it runs the search at
once instead) and Esc closes. Double-click opens a nest, and a context
menu offers Open, Delete (after confirmation) and Refresh. It only
browses saved nests; new nests are still created from the main window.

Windows tests drive the real form: page load, details for two nests,
Enter opening the highlighted one, the missing-archive message and Esc.
