fix: stop title filters from truncating a LinkedIn search early

fetchJobs ended pagination on `newOnPage === 0`, but newOnPage counts
jobs that survived the title filters. A page whose 25 cards all happened
to be German/Java/junior/non-software read as end-of-results and killed
the whole search, discarding every later page. The end condition is now
new raw data-entity-urn card ids, pre-filter, so what gets filtered can
no longer decide where the crawl stops.

Also add a name-only "Basel (broad)" search alongside the three geoId
ones. LinkedIn's guest search serves a different slice per query shape:
the Basel-city geoId query exhausts at 76 unique cards and never returns
some genuinely Basel-Stadt postings a name-resolved query does. PAS01's
"Full-Stack Software Engineer (60-80%)" in Basel (4461764782) was
invisible to all six Basel searches and reached the digest only because
the Bern query — also name-only — happened to return it. Union across
the Basel searches: 126 unique.
