[UI] Remote Control: Permission approval buttons need better spacing and positioning on mobile

Description

When using Claude Code's Remote Control feature from the iOS Claude app, the permission approval UI (triggered by Claude Code's permission system for tool calls) has usability issues:

1. The approve/deny buttons are positioned very low on the screen, requiring scrolling or awkward thumb reach
2. The buttons are too close together, making it easy to accidentally tap the wrong one

This is specifically about the Claude Code Remote Control permission prompt UI — the same permission gates that appear in the CLI terminal (Allow/Deny for tool calls) rendered in the mobile Remote Control interface.

Expected Behavior

Permission approval buttons should be:

• Positioned higher / more centrally on the screen for easy reach
• Spaced further apart to prevent accidental taps (especially important since approving the wrong action could be destructive)

Current Behavior

Buttons are clustered at the bottom of the screen with minimal spacing between them.

Why This Matters

Permission prompts are the most critical interaction point in Remote Control — accidentally approving a destructive action (or accidentally denying a safe one and breaking flow) has real consequences. The button layout should reflect this importance with clear, well-spaced, easy-to-reach targets.
