The dialog laid its pages out as a row of buttons across the top, which is
what AutoCAD does and what fits while there are four of them. The pages this
series adds take it to nine, and the names are translated into 21 languages —
a row of nine German or Russian page names does not fit at any dialog width
worth having.
The rail is now a vertical list down the left, the dialog is 880×620 rather
than 540×560, and the content pane scrolls on its own.
Which page was open is now remembered. With four pages, reopening on General
was a shrug; with nine it means hunting for the one you were last in.
The ribbon's Options tool has existed all along — `ToolDef`, icon and all —
but was marked `#[allow(dead_code)]` and never added to a group, so the
dialog could only be reached by typing OPTIONS or from the start page. It
now sits in Manage ▸ Application, beside About.
No settings change in this commit; it is only the shell the rest needs.

UI chrome (dropdown carets, undo/redo, checkmarks, close/menu/osnap,
layer/file-menu icons) and ribbon tool icons were drawn as Unicode
glyphs. Desktop fills missing glyphs via system-font fallback, but the
web build bundles only Fira Sans with no fallback, so they rendered as
empty tofu boxes (issue #116).
Add a shared src/ui/icons.rs (SVG-backed, tintable) plus bundled assets,
and switch every glyph site and IconKind::Glyph tool def to SVG.
