Extends the resizable="true"/minw/minh markup grammar's coverage past
MarkupDocument's own parse tests to the two host seams a resizable
plugin panel actually flows through, proving no host-side wiring beyond
what MarkupDocument.Build already sets on the panel was needed:
- RetailWindowManagerTests: a resizable="true" markup panel accepts
RetailWindowManager.ResizeTo within its minw/minh floor (and clamps
to it below the floor); a plain (non-resizable) markup panel refuses
— Width/Height unchanged and no Resized event, exactly today's
fixed-size behavior.
- RetailWindowLayoutPersistenceTests: a resizable panel's dragged size
round-trips through save/restore into a fresh session, and a saved
size below the panel's CURRENT minw/minh floor (a legacy save, or a
plugin update that raised its floor) clamps UP to the floor on
restore rather than restoring the too-small legacy value.
Mutation proof: reverted MarkupDocument.cs to its pre-feature state and
reran the new tests — the two RetailWindowManagerTests cases failed
(the old UiNineSlicePanel ctor default of Resizable=true/MinWidth=40
let the "fixed" window resize and let the "resizable" window shrink
below the new floor), and the persistence floor-clamp case failed
(80x60 came back instead of clamping to 200x150). The plain
save/restore round-trip case passed either way — the old ctor default
was already resizable, so it exercises a real but coincidentally
already-covered path; kept for its own documentation value. Restoring
the implementation returns 256/257 (1 pre-existing unrelated skip) on
the full Markup/PluginSidePanel/RetailWindow/Anchor-filtered App suite
and 9/9 on the MossTank markup-filtered suite, both green.
