Design: every offer verb has a hint, shown on hover — and the status line wraps

Mirror of snaporca 2b3e890165 (DesignPanel.cpp applied as a patch; parity 30 / 16, shared
files byte-identical).

All 86 verbs now carry a hint: 55 extracted from the C++ tool definitions so the offer and
the armed-tool hint cannot drift, 31 written by hand. One wxEVT_MENU_HIGHLIGHT binding
shows the hovered verb's hint in the status line. The generator asserts that no wired verb
lacks one.

Also: all 200 status writes go through set_status(), which wraps instead of clipping at the
panel edge; and the empty-document hint is called from on_tab_shown() as well, since
after_tree_edit() never runs on a freshly opened tab.

Verified on the rig.
