fix: disable RLS concern after disabling database RLS

 RLS has been disabled at database level in Supabase.

 The RowLevelSecurity concern was trying to set session variables
 which caused errors with the connection pooler.

  Since Rails already handles organization scoping at application level,
  we don't need the RLS concern anymore.
