Records engineer-reported outcome (applied_success|applied_failed|
applied_partial|dismissed). Enforces transition rules (partial → success/
failed allowed; terminal outcomes return 409) and notes requirements
(applied_partial requires notes).
Sets verified_at on success/failure, stamps applied_at if not already
set (handles the case where the AI [FIX_OUTCOME] marker fires before
the engineer clicks Apply).
Also fixes pre-existing test-infrastructure bug: network_diagram.py used
bare string server_default="'[]'" for JSONB columns, which asyncpg
rejects during test schema creation. Changed to text("'[]'::jsonb") to
match the pattern used by script_template.py.
