Improve barcode detection in documents with graphics and text by implementing
a multi-strategy horizontal slicing approach:
- Split documents into overlapping horizontal sections (5,4,3,2,1, or full)
- Decode each section separately to isolate individual barcodes
- Use 2% overlap between sections to avoid missing boundary codes
- Return the strategy that detects the most barcodes
- Early exit optimization when fewer codes are found
Also fix error handling to use Error objects instead of string literals.

Remove canvas splitting logic since zxing-wasm natively supports multiple barcode detection with maxNumberOfSymbols parameter. Reduces code by 69 lines and improves performance by requiring only a single decode call per canvas. Set maxNumberOfSymbols to 10 for realistic utility bill use case.

Replace @zxing/browser with zxing-wasm for better performance and smaller WebAssembly bundle size (919KB). Added middleware exclusion for .wasm files to prevent i18n routing interference.
