Route Prismatic file import through the shared upsert

Browse Source 
The manual JSON file import had its own insert/update loop; it now maps to
PowderCatalogItem and calls IPowderCatalogUpsertService.UpsertAsync — the same
path the Columbia API sync uses — so there is a single upsert/diff implementation
(and the file import now gets inventory propagation for free). Items are tagged
Source = "Manual JSON Import".

Also makes the shared upsert merge-not-wipe: it only overwrites a field when the
incoming feed provides a value (non-blank string, price > 0, nullable HasValue),
so a partial feed like the Prismatic scrape (no cure/chemistry) can't null out
data another source or enrichment populated.
