Feat(QRCode): Enhance 'Scan QR Code From Screen' notifications # #1250

[hiddenSharp429]

Improve the clarity of notifications in the QR code scanning feature:

1. Permission handling:
   • Show notification when screen recording permission is missing
   • Automatically open system settings for permission grant

2. Enhanced scanning status notifications: When no QR code found:

   • Title: "Scanned X displays"
   • Subtitle: "No QR codes found"
   • Body: "Try adjusting the QR code position on your screen"

   When invalid QR codes found:

   • Title: "Found X QR code(s)"
   • Subtitle: "No valid Shadowsocks URLs"
   • Body: "QR codes found are not Shadowsocks configuration"

   When valid QR codes found:

   • Title: "Found X Shadowsocks URL(s)"
   • Subtitle: "Scanned X displays, found X QR codes"
   • Body: "Successfully added X server configuration(s)"

@lkebin I saw a recent PR mentioned you, Could you help review this PR?

[hiddenSharp429]

The following error was encountered during the CI build process:

Makefile.am:21: error: Libtool library used but 'LIBTOOL' is undefined

This seems to be a configuration issue with the build system and has nothing to do with my code changes. Should I resubmit the PR?

@lkebin Hi maintainers,Could you please help to re-run the workflow? I noticed the build failed due to some configuration issues, but I don't have the permissions to trigger a rebuild myself.Thank you for your time and code review!
