Add support for testing Elicitation capability

[olaservo]

Is your feature request related to a problem? Please describe.
When developing MCP servers that need to request user input during operations, developers will need a way to test these interactive workflows in the Inspector.

Describe the solution you'd like

Add support for elicitation in the MCP Inspector UI:

• Display elicitation requests from servers in the UI
• Provide input fields for users to respond to elicitation prompts
• Show the flow of elicitation exchanges in the request history
• Support both CLI and UI modes for testing elicitation

Describe alternatives you've considered

Additional context
Depends on TypeScript SDK support.
