Add passkey login and favorite search termsHEADmaster

Single-user auth: any registered passkey logs in as the owner. First
registration needs a one-time token that the app writes to
data/registration-token when no passkey exists yet; once logged in,
more passkeys can be added without a token.

Logged in, /favorites manages a list of terms (e.g. band names).
Events whose title or artist contains a term (NFKC + case-insensitive)
get a ★, and the event list gains an "お気に入りのみ" filter.
