feat(service-terminal): enhance terminal functionality with quick actions and doc redirection

[TheoGrandin74]

Summary

• Added "CLI documentation" link redirection
• Added a "Banner" in the terminal to inform people on how to access the cli on their local machine, with buttons to copy the command
• Added a true empty state when the CLI is not working (because there's no pod for example)
• Added new size in input search to match button size
• Updated the text of the "search a pods" search to be more specific/informative on what's it really doing
