Fix: Added defaultRunInput to .actor/actor.json (Layer 3 of §226).
Symptom: Apify Store auto-QA runs with empty input hit Layer 2 fallback (DEFAULT_USERNAME) instead of running with the defaultRunInput the schema advertises.
Fix: defaultRunInput mirrors schema defaults 1:1 (username, raw), so empty-input runs now execute the schema-declared defaults.
Paid tier: 3 PPE events charged per run (account-basic-info-result + account-original-count-result + account-principal-info-result) to mirror SIÁN's per-event pricing.
