Fixes recurrence #4 of the mobile terminal excess character-spacing bug: SessionTerminal and TerminalModal now force a second genuine xterm font remeasure AFTER fitAddon.fit() settles the post-fit column count, since handleResize() never re-bakes DomRenderer's letter-spacing compensation itself.
- SessionTerminal.tsx: call forceTerminalFontRemeasure() again after fit()/sendResizeMessage() in the resize handler, re-baking spacing against the settled (post-fit) column count instead of the stale pre-fit one.
- TerminalModal.tsx: same second forceTerminalFontRemeasure() call after fitAddon.fit()/sendResize() in its resize handling path.
- Expanded SessionTerminal.test.tsx and TerminalModal.test.tsx coverage to assert the post-fit remeasure occurs.
- Added docs/solutions/ui-bugs/xterm-options-noop-remeasure-after-font-settle.md documenting recurrence #4 root cause (DomRenderer._setDefaultSpacing() never recomputes from handleResize()).
- Added changeset fn-7567-mobile-terminal-spacing.md (patch, category fix).
