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.

Added cache revalidation to ensure ViewLocationCard reflects uploaded
proof of payment when navigating back from ViewBillCard:
- Server-side: Added revalidatePath() to upload actions in billActions
and locationActions to invalidate Next.js server cache
- Client-side: Added router.refresh() calls in ViewBillCard and
ViewLocationCard to refresh client router cache after successful upload
This maintains the current UX (no redirect on upload) while ensuring
fresh data is displayed on navigation.
