feat(payment): finish Zibll key contract and wire checkout gateways

Drop dual-read payment runtime fallbacks, align PHP schema to Vue keys,
read gateway credentials only from aksrt_settings with enable toggles,
expose configured adapters at checkout, fix credits pay signatures, and
apply order expiry settings. Wire orphan order/card-pass/withdrawal
schema pages; delete unused Payment* wrappers.
