gsxdsm 11c4120705 FN-6659: keep xterm font metrics symbols-free ...

Keep terminal wide-glyph fallback out of xterm's measured font path while preserving Nerd Font symbols in DOM rendering.

- Split terminal font resolution into symbols-free xterm font families and scoped glyph fallback families.
- Apply the glyph fallback CSS variable to both TerminalModal and SessionTerminal surfaces.
- Update regression coverage and the documented mobile xterm wide-glyph recurrence analysis.
