Trigger manual refresh/analysis for a domain and all its topics

Set to true when the user explicitly clicked refresh: the request is recorded as a manual trigger and counts against the daily refresh limit. Omitted or any other value records a setup/creation trigger with no daily-limit check.

Target analysis queue. priority uses the high-priority lane; default uses the shared standard lane. When omitted, this endpoint always routes to the high-priority lane: both trigger sources it produces (manual and setup/creation) resolve to priority.
