Replace subprocess calls to wg genkey/pubkey with cryptography
library's X25519PrivateKey. This eliminates the wg CLI dependency
for key generation, fixes device creation on machines without
wireguard-tools, and removes the event loop blocking that caused
WebSocket disconnects during device creation.

Also fix E2E test teardown to use a fresh engine for cleanup,
avoiding cross-event-loop issues with asyncpg connection pools.
