Waste, bikes, and padel — login with AldenWallet through the city OIDC bridge.
Sign in as a new resident (PID name and city) or as a returning citizen (wallet recognition only).
Signup uses the bridge authWithClaims client so the ID token carries given_name, family_name, and resident_city. Returning login uses the authOnly client — the bridge recognizes the wallet key and does not force a presentation.
