Give proportional fonts a cell as wide as their widest glyph, keep glyph slots inside the cache, and fall back to the built-in font when a terminal font still can't load. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

What
Proportional terminal fonts now get a cell as wide as their widest glyph.
Glyph slots stay inside the cache.
Fonts that still can't work use the built-in font.
Why
Fixes #10848.
The font has a normal space, but the width guess picked a 3 px cell.
Glyphs did not fit, slots ran past the cache, and the terminal raised during boot.
display.cchangeOn a real CLUE, the issue's font now boots as the terminal, with wide gaps between letters.
Limits: proportional text is monospaced, so gaps are wide and some glyphs clip. A font with two widths that aren't 1:2 uses the built-in font. Not fixed here:
bits_per_pixel>= 6 still crashes at boot, and font deinit leaks the glyph bitmap.@lynt-smitka your cp-desktop-lab reproduced this crash and tested the fix before any hardware run.

Claude wrote the patch and ran the lab and CLUE tests. I directed the work and reviewed the results.
