gsxdsm e347062e1f FN-7603: force xterm DOM-based char measurement to fix mobile terminal spacing ...

Fixes recurrence #5 of mobile terminal inter-character spacing by unifying xterm's cell-width measurement pipeline with WidthCache's DOM-based glyph measurement, validated against real xterm instead of the jsdom mock.

- Add withDomBasedTerminalCharacterMeasurement() in terminalPreferences.ts: transiently hides window.OffscreenCanvas during terminal.open() so CharSizeService's constructor throws and self-selects its own DOM-based fallback strategy, unifying dimensions.css.cell.width with WidthCache.get('W') measurement
- Wire withDomBasedTerminalCharacterMeasurement() around terminal.open() calls in SessionTerminal.tsx and TerminalModal.tsx
- Add FNXC:Terminal comments documenting the Canvas-vs-DOM measurement divergence root cause, grounded in the installed @xterm/xterm@5.5.0 source
- Add docs/solutions/ui-bugs/xterm-options-noop-remeasure-after-font-settle.md recurrence #5 section
- Expand TerminalModal.test.tsx coverage for the new measurement-forcing behavior
- Add changeset fn-7603-mobile-terminal-spacing.md (patch, fix)
