Make the validator order deterministic, so the current activated validator is the first on the list

[boulder225]

🎯 Problem to be solved

• The current validator selection process after recombination is not the first one in the list, causing confusion and potential issues in managing clusters with many validators.
• Uncertainty about the possibility of depositing for a different validator and the need for a deterministic order to prevent double deposits and facilitate programmatic key generation.

🛠️ Proposed solution

• [ ] Check the criteria for validator ordering post-recombination to understand why the currently activated validator isn't the first on the list.
• [ ] Make the validator order deterministic by sorting based on the pubkey, filename, or other attributes.

I think a charon info command would go a long way in making things like this viewable. It could check a chain for status too, and pretty-print or json-print the info to console for people to eyeball.
