[ArchangeLillith]

Additions

• Added modal functionality.
• PDF integrations, pulling from S3.
• Expanded the AdminPanel with most desired features for now.
• Added backend support for handling CRUD operations for:
  • Comments
  • Authors
  • Searches
• Implemented ban user functionality.
• Added comment functionality (read/write); update/delete still in progress.
• Added middleware for author verification.
• Added logging functionality visible to admins; currently enabled on a select few routes.
• Integrated author functionality; every pattern now has an associated author.
• Enhanced styling across the application.
• Added the paid property to patterns and an icon to indicate paid patterns, including a tooltip that explains its meaning.

Deletions

• Removed all Toast notifications; unable to get them working.

Refactors

• Broke down large views into smaller, reusable components.
• Reorganized the file system: components for specific pages are now grouped into their own folders within the larger components directory.
• Cleaned up type definitions.
• Improved login and registration logic in the authentication flow.
• Autofocus added on the login input field; need to add the same for search functionality.
• Search by author is now functional.
• Refactored base (fetch abstraction) to handle errors more cleanly.
• Cleaned up various service implementations.
• Removed state types from all views and exported them from the types utility for cleaner TSX files.
• Refactored pattern fetches to automatically include associated tags and return them in a structured object.
• Extracted some reusable functions into a utility module.
• Consolidated most page states into a single state object rather than multiple single states.
