fix(tools): pass errorExtractor to extractErrorMessage and handle proxy error format

The executor was calling extractErrorMessage without the tool's errorExtractor
ID, so the tool-specific extractor was never used. Also add fallback for the
internal proxy route error format ({ error: "..." }) which none of the
Atlassian-specific patterns matched.
