Add toggle to disable auto-clearing slskd search history

Users who keep manual searches in slskd as reminders were losing
them when SoulSync auto-cleaned at 200+ entries. New toggle in
Settings → Downloads → Soulseek: "Auto-clear slskd search history"
(on by default, preserving current behavior). When disabled, both
the hourly cleanup automation and the full cleanup step skip the
search history maintenance.
