KCAI request - Enhance QR Filter to Support External Barcode Scanner Input

[DonKoko]

Description:
Extend the QR ID filter functionality to work with external barcode scanners by processing URL inputs into clean QR IDs.

Technical Requirements:

• Add URL parsing for shelf shortcodes
• Strip URL components to extract QR ID
• Support all filter operators (is, is not, contains, matches any, contains any)
• Maintain compatibility with existing QR scanning functionality

Implementation Details:

• Add URL detection and parsing logic
• Create QR ID extraction function
• Update filter input handling to process scanner input
• Ensure compatibility across all search/filter fields

Testing Scenarios:

1. Direct QR ID input
2. Full URL input from scanner
3. Various filter operator combinations
4. Multiple sequential scans
5. Edge cases (malformed URLs, invalid codes)
