paramminer: dedup by endpoint + param keys, not full URL string

[liquidsec]

Summary

paramminer's input dedup keys on the full URL string. When lightfuzz (or other fuzzers) cycle existing parameters through many probe values, each value mutation creates a URL string paramminer treats as a fresh test surface -- the same endpoint gets wordlist-tested dozens of times for the same effective param structure.

Overrides _incoming_dedup_hash to canonicalize on (event_type, scheme, netloc, path, sorted_param_keys) instead of the full URL. Value mutations of the same endpoint collapse into one test while structural variation (added keys, distinct paths, distinct hosts) remains distinct. paramminer_cookies and paramminer_getparams inherit the fix via class inheritance.

Empirical impact on lightfuzz-heavy presets: ~50% reduction in paramminer test cost, no change to discovered parameters or downstream findings.
