fix: lenient finding parsing — models return confidence as words/strings

Root cause of empty results: models emit findings with confidence as a string
('High') or cvss as a number, but the Finding struct typed confidence as f64, so
serde failed the ENTIRE array on any mismatch -> 0 findings every run.

extract_findings now parses into serde_json::Value and coerces each field
(string/number/word), normalizes severity, and accepts qualitative confidence
(High->0.9 etc). Verified live: whitebox on a vulnerable sample now yields
validated findings (IDOR confirmed by vote).
