Message:

Feature: paid posts slice 3, patron link + passkey (cookie-less)

The registration leg of the paid-posts flow (klonkt-demo-aki). A
visitor links once via Patreon and gets a pseudonymous passkey entitlement,
with no session and no patron identity stored.

• Dependency (approved): @simplewebauthn/server for verification, plus @simplewebauthn/browser vendored (UMD) so the page loads it with no CDN.
• New paid_entitlements table: {passkey, site, proven cents, expiry}. No name, e-mail or Patreon id, ever.
• Cookie-less throughout: the OAuth state and the WebAuthn challenge travel in signed blobs (CryptoBox), so nothing is kept between requests.
• Flow: GET /paid/link -> Patreon authorize; GET /paid/callback verifies the patron (verifyPatron exchanges the code, reads identity?include=memberships.campaign, checks patron_status + currently_entitled_amount_cents against the post's price), then hands out registration options + a signed blob carrying the challenge and proven cents; POST /paid/register verifies the passkey and stores the entitlement. The patron token is used once and discarded.

The gate button and the per-post unlock (assertion) are slice 4; this
leg is what that flow calls to register a passkey on demand.
