Description

This PR integrates Google Drive file loading and saving functionality directly into the Notes app. Users who have authenticated with Google can now open plain text files from their Drive, edit the content, and save the changes back.

Key changes include:

• New "File" Menu Options: "Open from Google Drive..." and "Save to Google Drive" have been added to the main dropdown menu in the Notes app.
• "Open from Drive" Modal: A new modal appears that lists all editable plain text files from the user's Google Drive root, allowing them to select a file to load.
• Smart Save Logic: The "Save to Google Drive" function is aware of the file's state. It will create a new file (prompting for a name) if the document is new, or it will update the content of the existing file if it was opened from Drive.
• New Backend API Endpoints: Added dedicated API routes (/api/files/gdrive/create and /api/files/gdrive/[fileId]) to securely handle the creation, reading, and updating of files via the Google Drive API.

Thats amazing, couple adjustments needed. Such as moving it as main folder manager. Google Drive requirement for File Manager, and Save and Delete of CRUD operations.
