Bug fixes & improvements:

• Image Upload: Opening the image upload in a dedicated tab now prevents the popup from closing unexpectedly. Drag-and-drop and click-to-select both work reliably in the new upload page.

• Page Scan: Content scripts are now injected dynamically before scanning, so pages that were already open before the extension was installed no longer need a manual refresh (F5). An 8-second timeout prevents the scan from hanging indefinitely on restricted pages.

• Stability: Improved error handling across popup initialisation and background script messaging.

Bug fixes:
• Fixed an issue where the popup's buttons and tabs were unresponsive on some Firefox versions
• Improved error handling in the language initialisation routine
• Context menu entries ("Read QR Code", "Scan Page") now reappear correctly after browser restart
• Minor stability improvements to background script messaging
