feat: add ability to edit/add/delete files in the file tree

[xKevIsDev]

File/Folder Operations:

• Rename functionality with inline editing
• Create new files and folders with proper directory structure
• Delete files and folders with confirmation dialog
• All operations update the file tree state and handle errors appropriately

Drag and Drop Image Support:

• Accepts image files via drag and drop

• Converts images to base64 format for storage

• Shows success/error notifications for uploads

• Maintains proper file structure when dropping images

UI Improvements:

• Inline rename input replaces the file/folder name during editing
• Context menu for all file operations
• Visual feedback during drag and drop
• Toast notifications for operation status

we also need update the files from filestore for system to detect the change and add it to the user metadata for persistence.

Yep, I seem to have overlooked that part will update asap.

@thecodacus for now i have removed rename until we find a cleaner solution. Also file/folder creations/deletions will persist now.
