Replace flat UUID filenames with a browsable, dated layout (spec.md item 9):
<STORAGE_DIR>/<YYYY>/<MM>_<DD>_<dollars>.<cents><ext>, from the receipt date
and amount. Same date+amount collisions get a _1, _2, … suffix via exclusive
create (race-safe). New uploads only; serving is unaffected (blob-backed).

Go app for capturing and archiving HSA-eligible receipts: OIDC/PKCE auth
against Authelia, SQLite storage with dual-write (filesystem + DB blob),
mobile-first upload, and DB export.
Adds AI receipt classification: a config.json catalog of people and
categories (seeded into the DB on startup), a prompt builder that derives
name-order/initial variants from the data (with same-surname ambiguity
handling), and an Anthropic tool-use client behind POST /classify. Tests
run against a mock endpoint; a live integration test is env-gated to the
cheapest model.
