fix(B6): EXIT Magic Mode — reset PackagePurchaseMethod + close current cycle

B6: PackagePurchaseMethod was NOT reset when exiting Magic Mode.
This caused Guards G1-G3 to permanently block re-purchase.

Changes:
- user.PackagePurchaseMethod = None (allows re-purchase via G1-G3)
- currentCycle.IsCurrentCycle = false (ready for new cycle)

Note: membership.IsActive is intentionally preserved (Q19 — contract is one-time).
Features are preserved — DIFF will be applied on next purchase (Q20).
