Fix image rotation to use 360 degrees instead of 180

[Copilot]

Image rotation was limited to 180 degrees due to incorrect modulo operation (% 180 instead of % 360), preventing full rotation through all four orientations.

Changes

• ImageCropper.tsx: New component with correct 360° rotation logic

  • Rotate left: (rotation - 90 + 360) % 360
  • Rotate right: (rotation + 90) % 360
  • Proper typing with Area interface, SVG rotation icons

• Utility files: Added cropImage.ts and getImageUrl.ts for image processing

  • Configurable output format and quality
  • Rotation support in radians conversion

• Dependencies: Added react-easy-crop for cropping UI

// Before (bug)
onClick={() => setRotation((rotation + 90) % 180)}  // Only 0°, 90°

// After (fix)
onClick={() => setRotation((rotation + 90) % 360)}  // 0°, 90°, 180°, 270°

Fixes #60

In fastify you have to update image rotation that is on 180 deg in the POST /profile-picture route

Pull request overview

This PR fixes a bug where image rotation was limited to only two orientations (0° and 90°) instead of allowing full 360° rotation through all four orientations (0°, 90°, 180°, 270°). The fix changes the modulo operation from % 180 to % 360 in the rotation logic.

• Implemented new ImageCropper component with corrected rotation handlers using % 360
• Added utility functions cropImage.ts and getImageUrl.ts for image processing and URL generation
• Integrated react-easy-crop library for enhanced cropping functionality

The comment says "Convert a File object to a data URL" but URL.createObjectURL() creates a blob URL (e.g., blob:...), not a data URL (e.g., data:image/png;base64,...). Consider updating the comment to accurately describe the function's behavior: "Convert a File object to a blob URL for display".

Suggested change

	* Convert a File object to a data URL for display
	* Convert a File object to a blob URL for display

Memory leak: Object URLs created with URL.createObjectURL() should be revoked with URL.revokeObjectURL() when no longer needed to prevent memory leaks. In this component, a new object URL is created on every render when getCurrentImage() changes, but previous URLs are never cleaned up. Consider using a useEffect hook to manage the URL lifecycle:

useEffect(() => {
  const currentImage = getCurrentImage();
  const url = currentImage ? URL.createObjectURL(currentImage) : "none";
  return () => {
    if (url !== "none") {
      URL.revokeObjectURL(url);
    }
  };
}, [currentCroppingIndex, profilePicture, additionalPictures]);

The comment says "Create a cropped image from a source image URL" but this function only loads an image, it doesn't crop it. The actual cropping is done by getCroppedImg(). Consider updating to: "Load an image from a URL".

Suggested change

	* Create a cropped image from a source image URL
	* Load an image from a URL
