fix(jobbank-search): emit date key derived from posted in search output (#342)

jobbank search output was missing the shared contract's date field; it now emits date as YYYY-MM-DD derived from posted (kept unchanged), null when the feed item has no pubDate. The inline result mapping is extracted into an exported normalizeSearchItem (behavior-preserving) so the derivation is pinned by tests.
