Analytika: /auth sa uz nesleduje -- 1:1 duplicita landing eventu

Na /auth sa da dostat len plnym loadom stranky (vsetky interne
redirecty nan su REPLACE a beacon ich skipuje) a kazdy plny load uz
posiela event landing. Kazdy riadok /auth by tak mal dvojicku z toho
isteho loadu. Skip na frontende aj v _SKIPPED_PATHS (pokryje aj stare
cache-ovane verzie frontendu). Stare /auth riadky v DB ostavaju.
