resolve: sets status=resolved, helpful, resolution_notes, resolved_at;
flips FlowProposal.validated_by_outcome on helpful=True proposal walks;
closes linked internal ticket. PSA close is a Phase 2 stub.
escalate: marks session + internal ticket as escalated. PSA reassign
deferred to Phase 2.
escalate_without_walk: creates an immediately-escalated adhoc session
with no walked_path, used by the BuildAbortedNoKB → Escalate path.

record_step appends to walked_path JSONB and advances current_node_id
on flow/proposal walks; refuses adhoc sessions. update_notes replaces
walk_notes (used by adhoc walks for debounced autosave); 256KB size cap
to prevent unbounded JSONB growth. Both reject non-active sessions.

Three start_* functions creating L1WalkSession rows with appropriate
session_kind and target id. Engineers acting in L1 mode get
acting_as='l1_coverage' for audit; native l1_tech users get acting_as=None.
step/notes (T13) and resolve/escalate (T14) extend this file next.
