feat: expose deep-scan settings via API and persisted config

Adds scanner_http_ranges / scanner_http_probe_enabled / scanner_http_verify_tls
to Settings (persisted in scan_config.json, Options page defaults). /scan/trigger
accepts an optional body to override these per-scan; /scan/config GET/POST read
and persist the defaults. Port ranges validated at the API boundary.

ha-relevant: yes
