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.

Replace custom PDF417 generation (generateBarcode/renderBarcode) with zxing-wasm's writeBarcode for improved reliability and smaller codebase. Updated all 4 components (BillEditForm, PrintPreview, ViewBillCard, ViewLocationCard) to use new Pdf417BarcodeWasm component with ecLevel 5 for error correction.

Remove @zxing/browser and @zxing/library dependencies as they have been fully replaced by zxing-wasm. Delete old barcodeDecoder.ts file which is no longer used after migration to barcodeDecoderWasm.ts.

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.
