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.

Added read-only proof of payment display in bill edit form:
- Shows download link when proofOfPaymentType is "per-bill" and proof exists
- Uses TicketIcon with teal color for visual distinction
- Links to /share/proof-of-payment/per-bill/ download route
- Handles housekeeping case (no display if filename missing)
This allows users to view and download existing proof of payment
while editing a bill, improving transparency and user experience.

Changed proof of payment download link from old route structure
/share/proof-of-payment/[id]/ to new structure
/share/proof-of-payment/combined/[id]/
This aligns with the reorganized route structure that separates
combined and per-bill proof of payment downloads.

Fixed mixed inclusion/exclusion projection that caused error:
"Cannot do inclusion on field bills.proofOfPayment.uploadedAt in exclusion projection"
Changed projection to use exclusion-only:
- Exclude bills.attachment (not needed in upload context)
- Exclude bills.proofOfPayment.fileContentsBase64 (large file data)
- Include all other fields implicitly (including uploadedAt for existence check)
This reduces data transfer while maintaining MongoDB projection compatibility.

Added two download routes for proof of payment files:
1. Combined route: /share/proof-of-payment/combined/[id]/
- Downloads location-level proof of payment for all utilities
- Queries utilBillsProofOfPayment from location
- Optimized projection for efficient data transfer
2. Per-bill route: /share/proof-of-payment/per-bill/[id]/
- Downloads proof of payment for individual bills
- Parses composite ID format: locationID-billID
- Finds specific bill in location's bills array
- Returns bill.proofOfPayment
Both routes:
- Return PDF files with proper Content-Type and headers
- Handle 404 for missing locations/bills/proofs
- Use Base64 to binary conversion for file delivery
- Include Last-Modified header for caching
- Use optimized database projections

- Show upload section only when proofOfPaymentType is "combined"
- Updated field names to use new FileAttachment structure:
- utilBillsProofOfPaymentAttachment → utilBillsProofOfPayment
- utilBillsProofOfPaymentUploadedAt → utilBillsProofOfPayment.uploadedAt
- Updated FormData and input field names for consistency
- Improved code formatting and spacing throughout
This enables proper handling of the three proof of payment options:
- "none": No upload section shown
- "combined": Shows single proof upload for all utilities (this change)
- "per-bill": No upload section (handled per individual bill)
