Six integration cards and the lab-OCR dialog keyed their tone off `res.ok`.
A sync that imported nothing because every reading was refused rendered a
green tick and a count, and a re-scan in which every confirmed row turned out
to be a duplicate raised a green toast saying zero readings were saved.
Each surface now renders the outcome the route resolved: a tick only when
everything landed, a warning when some of it did not, an error when none of
it did, and a neutral note when there was nothing new. The lab-OCR toast
picks its variant the same way.
Replaces the directory-scoped import guard with one that covers the whole
component tree and pins per-file occurrence counts, so a listed file cannot
quietly add a second tick. Its docstring states what it cannot catch.
