fix: Asset Hub AccountId32 encoding for withdrawal edge functions

Deno npm shim breaks SS58 decoding in @pezkuwi/api type registry, causing PezspCoreCryptoAccountId32 to receive 48-byte SS58 strings instead of 32-byte public keys. Added inline ss58ToHex decoder and explicit hex-based nonce fetching to avoid all SS58 → AccountId32 conversions at the API level. Also adds P2P E2E test script (45/45).
