Feature/multiple folder support

[rahulharpal1603]

Fixes #161

Demo Video: https://www.youtube.com/watch?v=4EM2_lW2S54

Major Changes:

• Now user can select one or more folders to display on the home page.
• Added Refresh button to the home page as well as videos page to delete the Tauri cache and reload the page (useful when user adds or removes something from the folder and wants it to update)
• In the settings page, the user can control which folders to keep and which to remove.
• When a user removes a folder from the settings page, the thumbnails in that folder are also deleted
• When a user tries to add a folder which is already present, the user is shown an error.

Minor Bug Fixes:

• Fixed the sorting function for arranging in alphabetical order
• Album Error handling issues are fixed. Now duplicate album errors are shown like in previous versions.

Summary:

Backend enhancements:

• backend/app/routes/images.py: Improved the logic for deleting images and their thumbnails, and added a new endpoint delete-thumbnails to delete all thumbnails in a given folder. [1] [2] [3] [4]

Frontend updates:

• frontend/api/api-functions/images.ts: Modified generateThumbnails to accept an array of folder paths and added a new function deleteThumbnails to call the new backend endpoint. [1] [2]

• frontend/src/components/AITagging/AIgallery.tsx: Updated the component to use the new generateThumbnails function and handle multiple folder paths. [1] [2] [3] [4] [5] [6] [7]

Miscellaneous:

• frontend/package.json: Renamed the project from "tauri-app" to "PictoPy".
• frontend/src-tauri/src/services/mod.rs: Updated the functions get_all_images_with_cache and get_all_videos_with_cache to accept an array of directories instead of a single directory. [1] [2] [3] [4] [5] [6] [7]
