feat(plane): stage visibility on board + verdict status UUIDs

Feature 3 + Feature 2 infra. Extend the global PLANE_STATES with the 6 new
enduro status UUIDs (architecture/development/review/testing + approved/rejected),
remap STAGE_TO_STATE so the 4 mid-pipeline stages move the issue across its own
board column instead of all sitting in In Progress, and add the
set_issue_stage_state() helper. Needs Input / In Review / Blocked keep their own
explicit setters and stay higher priority. TODO(ORCH-10): statuses are per-project;
resolve per project when more projects are onboarded.
