The button let users convert a text shape's inline styles into a
typography asset even when the shape's font-id couldn't be resolved
(e.g. a custom/team font that was removed or isn't loaded), silently
baking a missing font into the new typography asset.
Guard the button on the font actually resolving via
app.main.fonts/fontsdb, in addition to the existing checks (no
typography or token already applied, single selection).
Added e2e coverage for all four conditions that must independently
hide the button: missing font, applied typography asset, multiple
selection with differing values, and applied typography token.
