Version 1.1.7

This update fixes an issue where the QR code could not be generated due to the QR library missing from the extension package.

What’s new:
• Replaced qrcode.min.js with the unminified qrcode.js for Firefox compatibility.
• popup.html updated to correctly load qrcode.js.
• Removed unused meta CSP tag that conflicted with Firefox’s extension CSP handling.
• Updated internal version references to 1.1.7.
• General refinements to extension packaging for AMO compliance.

No functional feature changes were made beyond ensuring QR code generation works correctly in Firefox.
