CSUB-638: Add chain/era info to the Status command

[pLabarta]

Description of proposed changes

This PR makes some changes to the status command to introduce an option to show the Chain's status.

New behavior:

• If used with no flags, it will just print the chain status (block tip, last finalized, era info)
• If used with the --validator [address] flag, it will show that validator status
• If used with both flags, --validator [address] --chain, it will show information about both the chain and the validator

---

Practical tips for PR review & merge:

• All GitHub Actions report PASS
• Newly added code/functions have unit tests
  • Coverage tools report all newly added lines as covered
  • The positive scenario is exercised
  • Negative scenarios are exercised, e.g. assert on all possible errors
  • Assert on events triggered if applicable
  • Assert on changes made to storage if applicable
• Modified behavior/functions - try to make sure above test items are covered
• Integration tests are added if applicable/needed

Added some questions, possibly need changes.

Overall everything looks good to me. It might make sense to rename the cc-cli/src/utils directory to cc-cli/src/lib to reflect the growing importance of that part of the code base.
