## Summary by CodeRabbit

* **New Features**
* Added support for configuring multiple server hosts across backend and
frontend settings.
* Enhanced deployment and Helm chart configuration to allow specifying
multiple ingress hosts.
* Updated admin and configuration interfaces to display and manage
multiple server hosts.

* **Improvements**
* Improved URL generation, OAuth, and worker service logic to
dynamically handle requests from multiple hosts.
  * Enhanced captcha verification to support multiple allowed hostnames.
* Updated frontend logic for platform-specific server base URLs and
allowed origins, including Apple app domains.
  * Expanded test coverage for multi-host scenarios.

* **Bug Fixes**
* Corrected backend logic to consistently use dynamic base URLs and
origins based on request host context.
