Fix/redis password url encoding

[tharu-jwd]

Description

Wrap REDIS_PASSWORD with encodeURIComponent when building the fallback Redis URL.

Related Issue

Fixes #569

Motivation and Context

If REDIS_PASSWORD contains #, Node's URL parser treats it as a fragment and throws TypeError: Invalid URL. The relay fails to start with no useful error message. encodeURIComponent handles # and any other special characters safely.

How Has This Been Tested?

Verified locally that new URL() throws with a raw # in the password and succeeds after percent encoding it.
