fix(android): detekt TooManyFunctions on AuthStore (14/11)

CacheSettings persistence in b438772 pushed AuthStore from 12 to 14
functions. Same shape of fix as PlayerController (484ad6c-era):
@Suppress at the class with rationale — function count scales with
the pref count, splitting would scatter shared dao/scope/json
plumbing for no gain.
