Final Class Software-backed device signer key storage for dev/test environments.
This implementation generates P-256 keys in-memory, matching the official Crossmint RN SDK’s SoftwareDeviceSignerKeyStorage used in Expo Go and development builds where native hardware-backed storage is unavailable. Do not use in production. Keys are stored in memory and lost when the app process terminates.
