chore(branding): drop wardrobe tier to guest for local testing [LOCAL PATCH]

Wardrobe landed with requiredTier: 'beta' — correct for production,
but in the local dev loop the user's account is 'standard' and
clicking into /wardrobe/garment/[id] or /wardrobe/compose gets blocked
by the AuthGate with "Dein Zugang: Standard · Benötigt: Beta".

Flip to 'guest' to match the existing local tier-patch pattern that
already covers 55 of the 63 apps (see git log for earlier patches,
and memory note `project_tier_patch_resolved`).

Marked inline with `// LOCAL TIER PATCH — revert to 'beta' before
release` so the pre-release grep sweep finds it alongside the others.
