Add autogenerate_domain API parameter for applications

Allows API consumers to control domain auto-generation behavior. When autogenerate_domain is true (default) and no custom domains are provided, the system auto-generates a domain using the server's wildcard domain or sslip.io fallback.

- Add autogenerate_domain parameter to all 5 application creation endpoints
- Add validation and allowlist rules
- Implement domain auto-generation logic across all application types
- Add comprehensive unit tests for the feature
