ActionCampaign service exposes admin CRUD plus a per-user composer
(getActiveForUser) that fans out a per-step completion check against
the existing per-user model for each ActionStepKind: VideoView for
WATCH_VIDEO, CampaignEmail for SUBMIT_INFLUENCE, PetitionSignature
for SIGN_PETITION (matched by signer email), Ticket for RSVP_EVENT,
ShiftSignup for SIGNUP_SHIFT, ChallengeTeamMember for JOIN_CHALLENGE.
CUSTOM and VISIT_LINK steps complete only via explicit self-report.
An existing ActionStepCompletion row also short-circuits the check
so manual marking and idempotency both work.
Volunteer dashboard aggregator at GET /api/volunteer/dashboard
composes the active campaign with the user's profile, referral info,
upcoming featured event, training shifts (Shift.kind='TRAINING'),
ticketed events the user holds, an engagement-counter point total
(placeholder until the Redis engagement score is wired in), and
resources tagged 'volunteer-resource' across Document/Video/Photo.
