1Password/Bitwarden items can carry several websites, but both backends
collapsed the item's urls[]/uris[] to the first origin that normalizes,
so browser_vault_fill refused every other explicitly saved origin with
origin_mismatch. Reordering the URLs in the manager just moved which
single origin worked.
VaultItemMeta now carries allowed_origins (every normalized, deduped
web origin; origin stays the first/primary one). Fill matching stays
exact-origin against that list — no wildcard, parent-domain or subdomain
inference — and the in-page synchronous check pins the origin actually
matched via build_fill_js(expected_origin=page_origin). App URIs such as
androidapp:// never widen the fill set.
