fix: DELETE /v1/scraper/jobs/delete/ fails on URL-based deletion due to solrEscape over-escaping

[sebiboga]

Problem: DELETE /v1/scraper/jobs/delete/ returns 503 when deleting by URL. solrEscape() over-escapes URL characters (/, -, :) causing Solr to reject with 400.

Example: DELETE {url: https://lseg.wd3.myworkdayjobs.com/...} fails with 503.

Fix in PR #1124: Use phrase query (url:"...") instead of solrEscape() for URL values. CIF path unchanged.

Impact: Breaks stale job cleanup in all scrapers using URL-based deletion.
