Description
When trying to use a Macaroon generated by the BakeMacaroon API, failure can occur if using a root_key_id < 18441921392371827000 ([4]byte starting with {0xFF, 0xEE, 0xDD, 0xCC}).
When using a macaroon with permissions for Loop, Pool, Faraday, and Litd that was baked with a root_key_id matching the above condition, AND calling an rpc from these services, an error is returned: "proxy error with context {rpc service}: invalid macaroon: macaroon service not yet initialised". LND rpc services can still be used with this macaroon.

Research direction
Start with the BakeMacaroon API and trace how a root_key_id beginning with {0xFF, 0xEE, 0xDD, 0xCC} is handled before RPC authorization. Reproduce the case using permissions for Loop, Pool, Faraday, and Litd, then verify those RPCs accept the macaroon while existing LND RPC behavior remains intact.
