The blacklist company slug now lives on the offers themselves. POST /joboffers
accepts firma_slug and stores it as supplied (deriving it from firma only when
omitted); it is persisted on jobangebote (schema + ALTER/backfill + index) and
returned in the Joboffer response. Blacklist matching prefers the client-supplied
slug over one derived from firma, so the indexing client controls the identity
used to block an offer. OpenAPI request/response schemas updated.
