[Issue]: Mobile close and help controls are below comfortable touch target size

[cha1latte]

Summary

Several mobile dismiss and help controls are smaller than comfortable touch targets, making repeated mobile use error-prone.

Severity: minor

Expected behavior

Mobile close, dismiss, and help controls should be sized and spaced for touch use, especially on overlays and setup blockers.

Actual behavior

Multiple mobile controls are very small. During audit, the New Chat connection gate close control measured about 23x23, the right panel close control about 27.6x27.6, and settings help icons about 12.75x12.75.

Steps to reproduce

1. Run upstream/refactor in the web shell.
2. Set the viewport to 320x568.
3. Open the new chat connection gate by choosing Conversation with no connections configured.
4. Inspect the close affordance.
5. Open Settings and inspect the right panel close button and inline help buttons.

Additional context

Audit covered 390x844, 430x932, 375x667, 320x568, plus desktop-to-mobile resize without refresh. This does not fully block mobile daily driving, but it makes repeated setup and settings work harder on touch screens.
