Handle zeroconf object payloads and format Docker container list; update changelog

[404GamerNotFound]

Motivation

• Avoid setup errors when zeroconf discovery payloads are received as objects instead of dict and ensure the discovery host/name are resolved correctly.
• Improve readability of the Docker containers sensor by inserting spaces after commas in the returned list string.
• Record the fixes in the project CHANGELOG.md under a new release entry.

Description

• Change async_step_zeroconf to accept Any and handle both dict and object discovery payloads, resolving host and name via getattr fallbacks when necessary.
• Preserve duplicate/abort checks and assign the resolved name to self._discovered_name for use in UI placeholders.
• Add a transformation in the remote script to format container names with spaces via containers=${containers//,/, } inside read_docker_stats.
• Add a v1.2.25 entry to CHANGELOG.md documenting the zeroconf and container-list changes.

Testing

• No automated tests were executed for these changes.
