fix(FN-2838): prevent mobile zoom on dashboard form inputs

- Add global `touch-action: manipulation` on html/body to reduce gesture-triggered zoom
- Set mobile input font-size to 16px for terminal, nodes, and scripts modal form fields
- Extend mobile CSS regression tests to assert the global touch-action rule
