FoxhuntClient now holds an AuthInterceptor<FileTokenStorage> and
all 11 typed service accessors use with_interceptor() instead of
bare Channel::new(). This ensures every outgoing RPC automatically
includes the JWT Bearer token when one is cached on disk.
The bare channel() accessor is preserved for LoginClient which
needs unauthenticated access for the initial login RPC.
