fix(lint): resolve pylint and pyright issues on egress-log-option

- egress.py: extract _render_match_entry helper to reduce nesting depth
- egress_addon_core.py: make request_method/request_headers keyword-only
  to satisfy too-many-positional-arguments; wrap long lazy import lines
- egress_addon.py: remove unused Route import; add pylint disable for
  import-error on sidecar-only mitmproxy/egress_addon_core imports
- dlp_detectors.py: remove dead _min_distance function (superseded by
  _closest_pair)
