gsxdsm 16b6e5decb FN-6638: stabilize mobile terminal font metrics ...

Stabilize terminal font metric remeasurement across mobile and attach surfaces.

- Add a shared terminal font metric wait helper that falls back from full font stacks to concrete individual font families before remeasurement.
- Reapply font options, refit, resize, and refresh SessionTerminal after font metrics settle to cover attached CLI terminals.
- Pin text-size adjustment on xterm measurement subtrees so mobile WebKit cannot inflate ASCII cell metrics.
- Extend terminal preference and rendering tests, documentation, and changeset coverage for the recurrence.
