Refactor Server CORS handlers and update picoserve to support method routing
- Refactored `Server.scala` to use the `.OPTIONS()` handler builder method from `picoserve` and deduplicated the `OPTIONS` CORS response logic into a common `getOptionsResponse` helper. - Fixed `org.limium.picoserve.Server` Java code to group handlers by path so that multiple HTTP methods (e.g. `POST` and `OPTIONS`) can be correctly routed to their respective processors for the same path. Tests now pass. Co-authored-by: hrj <345879+hrj@users.noreply.github.com>
