React Flight / Next.js RCE Advisory Fix

## Summary
Updated the educational-platform repository to address the React Flight / Next.js RCE advisory CVE-2024-52444 by upgrading Next.js to patched versions.

## Affected Project Analysis
- **Frontend**: Uses Next.js 16.0.1 (AFFECTED)
- **Backend**: NestJS application (not affected - no Next.js or React Flight packages)
- **Root**: Only utility dependencies (not affected)

## Changes Made

### Modified Files:
1. **frontend/package.json**
   - Upgraded `next`: `16.0.1` → `16.0.7` (patched version for 16.x)
   - Upgraded `eslint-config-next`: `16.0.1` → `16.0.7` (matching Next.js version)
   - React versions (`19.2.0`) remain unchanged - Next.js 16.0.7 automatically provides compatible patched React versions

### Lockfile Updates:
- **frontend/package-lock.json**: Updated to reflect Next.js 16.0.7 and eslint-config-next 16.0.7

## Implementation Notes
- No React Flight packages (`react-server-dom-*`) were found in the project, so only the Next.js upgrade was required
- React and React-DOM versions did not need manual updates as Next.js 16.0.7 supplies the correct patched versions automatically
- Dependencies were installed using `npm install --legacy-peer-deps` to handle pre-existing peer dependency constraints in the project
- The build encounters a pre-existing unrelated issue with the lightningcss module, not caused by this security update

## Security Verification
- ✅ Next.js upgraded to patched version 16.0.7 (required for CVE-2024-52444)
- ✅ No vulnerable React Flight packages present
- ✅ No additional React Flight packages need updating
- ✅ React and React-DOM versions compatible with patched Next.js

## Testing
- Verified Next.js 16.0.7 is correctly installed: `npm ls next`
- Verified eslint-config-next 16.0.7 is correctly installed: `npm ls eslint-config-next`
- Confirmed package-lock.json reflects patched versions
- Dependencies resolved without advisory-related errors

## Notes
The project has some pre-existing configuration complexity:
- Multiple lockfiles (yarn.lock, package-lock.json, bun.lock) at workspace level
- Pre-existing peer dependency warnings with react-reveal@1.2.2 requiring legacy-peer-deps flag
- Pre-existing lightningcss module issue unrelated to security updates
