Description

This PR implements the Custom Logo Feature, allowing administrators to replace the default Fast.BI logo with a custom company logo globally across the console.

Key Features:

1. Upload Mechanism: Administrators can upload a new logo by clicking and holding the main logo for 15 seconds. This triggers a hidden upload modal.
2. Persistence: The uploaded logo is saved to the instance/ directory and persists across sessions (assuming persistent storage is configured for the container).
3. Flicker-Free Loading: Implemented a backend context processor to inject the correct logo path (/ui-config/custom_logo or default) directly into the HTML templates at render time, ensuring no visual flicker occurs during page navigation.
4. Security: The upload endpoint (/ui-config/upload_logo) is protected and only accessible to users in the Admin or consoleAdmin groups.

Technical Details:

• Backend: Added Flask endpoints for upload and serving. Updated app.py with a context processor for logo_path.
• Frontend: Updated home.js to handle the long-press event and AJAX upload.
• Templates: Refactored all *.html files to use {{ logo_path }} dynamic variable.
