Delete 5 unused modules: Presence (untracked), LiveView ShutdownHandler (unused mixin), RateLimiterWrapper (pointless delegation), Passcode (only used by own test), MapLive.Utils (pure delegates). Fix ShutdownHandler to not call deleted Presence. Inline ParamUtils at call sites. Remove cachex dep and 27 stale entries from mix.lock. Clean commented-out Exq/Redis config from application.ex.
