lstTemplates was a direct child of tabTemplates with an explicit pixel
Size, computed once against this dev machine's tab-strip height under
its own DPI/font scale. On the operator's real machine, adding enough
templates pushed rows past the control's actual bottom edge -
maximizing the window didn't help, confirming it wasn't a screen-space
problem but a stale size assumption baked into the designer file (the
same root cause as the earlier add/remove-button visibility bug).
Moved the button strip + list into their own panel (pnlTemplateList),
with the buttons Dock=Top and lstTemplates Dock=Fill - the list's
bounds are now computed by the layout engine against the real
container at runtime, with no absolute size to be wrong about,
regardless of DPI/font scale/window size.
