[Feature Request] Lock permission dropdown in bypassPermissions mode to prevent accidental changes

Problem

When using claude remote-control --permission-mode bypassPermissions, the permission dropdown button ("Bypass permissions ⌄") is placed directly next to the text input area in both the desktop and mobile Claude apps.

It's very easy to accidentally click/tap on it while typing, which opens a menu with three options (Ask permissions / Auto accept edits / Plan mode). If you accidentally select one, the session loses bypassPermissions and there's no way to restore it without restarting the remote-control session.

This is especially frustrating on mobile where the tap target is close to the keyboard area.

Expected behavior

When a session is started with --permission-mode bypassPermissions, the permission dropdown should be locked/disabled so it cannot be accidentally changed. Or at minimum, add a confirmation dialog before downgrading from bypass mode.

Steps to reproduce

1. Start claude remote-control --name test --permission-mode bypassPermissions
2. Connect via Claude app (desktop or mobile)
3. While typing in the input box, accidentally click/tap the "Bypass permissions" button
4. Permission mode is silently downgraded — no way to restore without restarting

Suggested solutions (any of these would help)

• Disable/hide the dropdown when bypassPermissions is set via CLI
• Add a confirmation dialog: "Are you sure you want to change permission mode?"
• Add a way to restore bypass mode from the UI without restarting
