v0.2.3

• New: re-read data from a certificate. In the product COA editor, an attached
  certificate now has a Re-read data action that runs the AI reader over the file
  again and shows a review/diff — one tick per figure (batch, lab, date, purity, mass)
  that differs from what's saved — so you can backfill a blank field or correct a wrong
  one without retyping. Nothing changes until you tick it and click Apply, and it never
  touches the size, the attached file, or the verify link. Handy after a bulk import.
  Requires an Anthropic key (COA → Settings); off without one.
• New: sortable catalog list. The catalog-wide All COAs screen now sorts by
  Product, Lab, Date and Purity — one click on the column header — for scanning a whole
  catalog's certificates at a glance.
• New: smarter scan / import. Dropping a certificate now prefers the lab's real
  verification link and ignores compound-reference links (PubChem, NCBI, Wikipedia,
  ChemSpider, etc.) that some COAs print — so the "verify link" field no longer fills with
  a molecule-database URL. A file that contains more than one certificate (e.g. two
  size variants in one PDF) is flagged with a warning instead of silently reading only the
  first — you add the others by hand.
• New: in-box scan progress. While a dropped certificate is read, the upload zone shows
  a native spinner and locks, so a second click or drop can't fire a duplicate import.
• Change: the built-in lab suggestions were expanded and curated (Janoshik, Chromate,
  Krause Analytical, BT Lab Testing, TrustPointe, Freedom Diagnostics, MZ Biolabs, AccuMark
  Labs), with better host inference so a lab's link is recognized on scan. Any other lab
  still works as free text.
