feat(captain): allow agents to report Captain messages (#14799)

Adds a cloud-only flow for agents to flag incorrect or problematic
Captain (AI) responses. Right-clicking a Captain message surfaces a
"Report message" option that opens a dialog to pick a problem type and
add a description, persisted to a new captain_message_reports table for
the team to review.
