fix(fonts): skip preview API call for BDF bitmap fonts (#345)

Browse Source 
The font preview endpoint explicitly rejects .bdf files (glyph rendering
not implemented server-side), returning 400. The JS didn't know this and
called the endpoint for every selected font, causing a noisy 400 on load.

Guard added in updateFontPreview(): if the selected font ends in .bdf,
show "Preview not available for BDF bitmap fonts" and return early instead
of hitting the API.
