luci-app-https-dns-proxy: update to 2025-12-29-1

* update version to match principal package
* split the main config section into service configs and the global
  instance configs
* add support for the new source_addr option; @karl82 I'd appreciate if
  you could look at the WebUI and documentation and suggest improvements
  for description
* add WebUI support for all available configs in both global configs and
  per-instance/provider modal window
* bugfix: store bootstrap_dns options from the provider json file when
  adding a new instance
* if listen_addr or listen_port or source_addr are not set, display nicer
  text in the GridSection view than `none`.
