feat: Add Client-Side EXIF Data Sanitizer Tool

Description

This PR introduces a new EXIF Sanitizer tool to the suite under the Utilities category. It allows users to strip private EXIF metadata (GPS coordinates, camera model/settings, timestamps, and dates) from image files directly in the browser, matching the project's privacy-first client-side processing goals.

Fixes #358

Changes Made

1. Page Component

• New Page: Created EXIFSanitizer.jsx containing:
  • Drag-and-drop file upload using the custom useFileUpload hook.
  • Lossless Segment Strip: (JPEG only) Reads the file as an ArrayBuffer and parses the binary structure, dropping the APP1 segment directly. This strips EXIF/GPS tags without re-compressing or degrading the image quality.
  • Canvas Pixel Redraw: (All formats) Draws the image onto a clean canvas context and exports a fresh blob, natively stripping EXIF metadata, headers, and color profile segments from PNG, WebP, and JPEG files. Includes an export quality selection slider.
  • Privacy Banner: Informative client-side banner verifying that no image data leaves the user's browser.
  • File Size Comparison: Interactive comparison panels displaying the original and sanitized file sizes after processing.

2. Layout & Routing Registry

• Icons & Registry: Imported the Shield icon from lucide-react and registered the tool under the Utilities section in toolsData.jsx.
• Routing: Registered the /exif-sanitizer lazy-loaded route in App.jsx.

Verification and Checks

• Linter: Verified npm run lint passes with zero errors/warnings.
• Production Build: Verified npm run build completes and bundles files successfully.
