fix(auth): register SysSsoProvider so the sys_sso_provider table provisions

Without adding SysSsoProvider to authIdentityObjects (the manifest the Auth
plugin provisions), the table is never created and the sso plugin's writes
fail at runtime. Caught by the live E2E: with this, sys_sso_provider
provisions with the correct snake columns.
