Pull Request Overview

This PR adds an api:curl command to provide an example of authenticated API usage for testing purposes. The command mimics curl functionality with OAuth2 authentication and retry logic for 401 errors.

• Adds a new api:curl command with comprehensive curl-like options including method, data, headers, and response formatting
• Integrates with existing authentication system using OAuth2 tokens and automatic 401 retry mechanisms
• Registers the new command in the root command structure

The helper functions cloneHeader and readAllToString are defined but never used in this file. Consider removing them or documenting their intended purpose if they're meant for future use.

Suggested change

	func cloneHeader(h http.Header) http.Header {
	out := make(http.Header, len(h))
	for k, v := range h {
	out[k] = append([]string(nil), v...)
	}
	return out
	}
	func readAllToString(r io.Reader) string {
	b, _ := io.ReadAll(r)
	return string(b)
	}

Just a note - this is good for testing, but the old command actually invoked curl, whereas this is pure Go, so it may need a different name if it's ultimately wanted as a feature.

Sure! This is only to be used as an example command to test the client created in #260 - I won't keep this afterwards.

Closing this one, as #260 is now merged.
