feat(tests): add Detect Procedure UI, template suggested-procedure editing, lead review panel

Blue Team gets a Detect Procedure textarea in the test detail view,
mirroring Red's Attack Procedure field. Template create/edit forms
gain a Detect Suggested Procedure field for leads to curate directly.
Leads also get a Procedure Suggestions panel on the Tests page,
scoped to their own team by the backend, to approve or reject
suggestions extracted from submitted rounds.
