Add UI clarity for per-project GitHub configuration

## Summary
- Add visual indicator showing GitHub config is per-project, not global
- Users were confused thinking settings applied to all projects

## Changes Made

### 1. Added info box to GitHub Integration section
- Displays project name in configuration context
- Explains that each project can have its own repository
- Only shown when GitHub Integration is enabled

### 2. Component updates
- GitHubIntegrationSection: Added projectName prop and info box
- ProjectSettings: Pass project.name to GitHubIntegrationSection

## User Impact
Eliminates confusion about configuration scope - users now clearly understand
that GitHub repository settings are project-specific.
