feat: add services list command

[mugiwaraluffy56]

The CLI can import artifacts and run tests, but it cannot currently show which services are already loaded in a Microcks instance. That makes local debugging and CI troubleshooting harder than it needs to be, because the user has to open the web UI just to confirm what is available before running a test.

Microcks already exposes service repository APIs such as /api/services and /api/services/map, so this feels like a natural CLI capability.

A possible command could be:

microcks services
# or
microcks services list

The default output could be a simple table with fields such as:

• service name
• version
• type
• last update or import date, if the API response exposes it cleanly

A JSON output mode could also be useful for scripts, if that matches the direction maintainers want for CLI output.

A first PR could keep the scope focused:

• add service DTOs in pkg/connectors
• add MicrocksClient.GetServices
• add a Cobra command under cmd/
• reuse the same auth and context resolution pattern as existing commands
• add httptest coverage for the client method and command output
• update command documentation

This would also be useful groundwork for the LFX VS Code integration work in #255, since listing loaded services is one of the expected editor views.

@lbroudoux @yada @Harsh4902 would this fit the CLI roadmap? If yes, I can work on a focused PR for the first version.

Nice @mugiwaraluffy56 , this would also pair well with the --output=json work in #301 . The pkg/output/ formatter package I proposed there could be reused for services list JSON output, keeping the CLI output layer consistent across commands

[mugiwaraluffy56]

@cotishq thanks for the pointer!, #301 is still a proposal. so i'll keep the output logic self contained in this pr. if #301 lands, the services command can be refactored to use the shared formatter then.
