Fix file:// URL bug in HtmlJobSearcher — skip non-HTTP(S) URLs

After resolving relative hrefs against the base search URL, some ejobs.ro
links were producing file:/// URIs (e.g. file:///user/locuri-de-munca/...).
These were sent to cv-matcher-api and rejected with HTTP 400, causing 0 matches.

Added a scheme guard after URI resolution to skip any URL that is not
http:// or https://, preventing malformed URLs from reaching the matcher.
