fix(auth): move SecureRandom out of static field for native-image compat
CI / Build Native (push) Successful in 7m25s
Details

Browse Source 
GraalVM native-image rejects static fields of type Random/SecureRandom
(their internal state is captured at build time and can't be replayed
deterministically). Move the instance into generatePassword() as a
local variable - it is only used once at startup anyway.
