Carlos Garcia f90a2ee863 feat: semantic deduplication of multiple photos of same receipt ...

After parsing all receipts, identify photos that are different shots of
the same physical receipt by comparing amount + date + vendor similarity
(difflib ratio >= 0.6). When a duplicate is found, keep whichever photo
produced the most OCR text (clearest shot) and report the skipped ones.

Zero-amount receipts (OCR failed entirely) are excluded from semantic
dedup to avoid false positives.
