Lever: drop limit=100 — was silently capping Mistral and Palantir

Lever's public postings API returns the full site list in a
single GET; passing `limit=100` was a soft hint that turned
out to be a hard truncation. Verified live:

  Mistral:  upstream 162, cached 100 (-62)
  Palantir: upstream 226, cached 100 (-126)
  Dnb:      upstream 86,  cached 86  (full, only because small)

Greenhouse and Ashby use the same "single GET, take everything"
pattern with no `limit` param — Databricks lands at 813 jobs
fine. The `limit=100` here was just an arbitrary value from
when the Lever provider was added; no specific reason. Drop it
and trust the API.

Memory is fine: the largest public Lever board we've measured
is in the low hundreds, and the worker chunks DB writes at 30
either way.
