Fix Docker static files permissions for production deployment

## Issue Fixed:
- Static files collection failing with permission error in Docker container
- Error: `PermissionError: [Errno 13] Permission denied: '/app/staticfiles/js'`
- Occurs when running `python manage.py collectstatic` in production

## Solution Applied:
1. **Enhanced Dockerfile**:
   - Create `/app/staticfiles` and `/app/media` directories explicitly
   - Set proper ownership with `chown -R django:django /app`
   - Ensures directories exist with correct permissions before user switch

2. **Improved entrypoint.sh**:
   - Added `mkdir -p` to ensure directories exist at runtime
   - Creates directories before attempting static files collection
   - Provides fallback if directories weren't created in Docker build

3. **Updated Documentation**:
   - Added troubleshooting section for static files permission error
   - Explains the fix and prevention methods

## Benefits:
- ✅ Resolves Docker container permission issues
- ✅ Works with non-root user (security best practice)
- ✅ Handles both build-time and runtime directory creation
- ✅ Maintains proper file ownership for Django operations

This should resolve the collectstatic permission error in Dokploy deployment.

 **Solution**: This is already fixed in the latest version. The production settings now use console logging only, which is Docker-friendly and works with Dokploy's log viewing system.
