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

Here are all the potential values for the state:

export declare const ServiceStateDto: {
    readonly STARTING: "STARTING";
    readonly RUNNING: "RUNNING";
    readonly ERROR: "ERROR";
    readonly STOPPING: "STOPPING";
    readonly STOPPED: "STOPPED";
    readonly COMPLETED: "COMPLETED";
    readonly WARNING: "WARNING";
};

Do we really want to fall back to "We could not launch the CLI for this service because it's not running." in all cases except for Stopped and Error?

[TheoGrandin74]

Well my approach is maybe a bit too simplistic, but most of the time user can't launch the CLI because there are no pods in their service, which is when services are either stopped or in error most of the time. I could have something for "Completed" also, but for the other states I'm not sure the CLI will fail because of a lack of pods 🤔

[TheoGrandin74]

Changed it to something more broad than just "Because it's not running" to avoid some confusion in some cases, I think it can suffice for now!
