Serve an OpenAccess descriptor at /.well-known/openaccess.json (#95)

Lists TronBrowser on OpenAccess hubs (openaccess.logicsrc.com) so people can
link it with OAuth 2.1 + PKCE and it honours the shared
profullstack.com/all-access entitlement. The Ed25519 public key here is
the app's credential for reporting sales; the private half is in the
logicsrc teams vault openaccess-app-keys--prod. Scopes are empty for now:
the reserved openid, email and entitlements scopes need no listing.

Spec: https://logicsrc.com/openaccess
