feat(desktop): build releases in a panel beside the Drawing Sets lists

The modal release dialog is replaced by ReleasePanel, docked beside the
Library and Sets tabs and shared by both. A double-click or Enter adds a
set at one kit or a library drawing on its own at the entered quantity;
adding one already listed adds to its quantity. Lines are edited in
place with a remove button, and the nests it will make preview live.

Each group now merges into a matching Draft nest by default: the only
one, or the most recently saved of several (chosen in the row); a draft
open in a tab blocks Make Nests instead of making a parallel nest.
Nest after release is remembered per user. Edit Set and Edit Drawing
move to their buttons and right-click menus.

The Drawing Sets window is now an unowned top-level window with its own
taskbar entry and remembered bounds, closed with the main window; a
release not yet made survives closing it, and Make Nests brings the
main window forward. ReleaseSetForm remains as a thin dialog host for
releasing from Nest > Add from Drawing Library.

 every drawing's required quantity, the selected engine, sheets from the nest's
 plate defaults and plate-size options, as the Auto Nest dialog would offer them.
 A layout is kept only when it is valid; otherwise the nest is saved without
 sheets and its status says "Auto Nest could not keep a layout: open it and run
-Auto Nest". The status column lists each group's sheets and utilization, and any

 copies left unplaced, which stay as remaining quantity. Unticked, new nests are
 saved without sheets and merged drafts are left cleared for Auto Nest.

-bound to its server record, and the release (with the release notes) is
-recorded. A release with drawings on their own first checks that the server can
