feat(14-01): record vendor calls with summer parity:upstream and replay them offline

Browse Source 
- WriteUpstream masks vars, hashes long base64 JSON strings and refuses unmasked Authorization/X-Api-Key
- multipart requests recorded as ordered parts; the fake compares parts and hashed payloads
- loopback CONNECT recording proxy with a local ECDSA parity CA, script and forward modes
- parity:upstream command, README and parity docs
