- devserver bootstraps via one-shot 'paskia init' when no database
exists (multi --rp-id, --rp-name/--auth-host/--origin apply to the
default realm), then runs plain 'paskia' serve which reads all realm
configuration from the database; legacy *.paskiadb is adopted by
serve without init.
- Caddy origins iterate all bootstrap rp-ids.
- vite.config.js accepts a comma-separated PASKIA_AUTH_HOST list and
proxies /.well-known/webauthn to the backend so ROR works in dev.
- caddy/auth/setup forwards /.well-known/openid-configuration and
/.well-known/webauthn to paskia (they must not be swallowed by a
static /.well-known/* file handler); Caddyfile.dev updated to match
the generated dev config.
