Fix DNS UI forms to support Enter key submission and improve PDNS test framework

- Add @finish handler to DNS form components (AddDnsServer, DeleteDnsServer,
  CreateDnsZone, DeleteDnsZone, CreateDnsRecord) to enable Enter key form
  submission in addition to Ctrl+Enter
- Change submit buttons from @click to htmlType='submit' for proper form
  submission handling
- Improve PDNS test framework with polling mechanism to wait for PDNS readiness
- Add pdns_unavailable flag to gracefully skip tests when PDNS is not reachable
- Add setUp method to check PDNS availability before each test
