Improve inspect command with optional server name

- Make server_name argument optional for inspect command
- When no server specified, show helpful panel with options
- Prompt user to confirm launching raw MCP Inspector
- Provide clear guidance on inspecting MCPM-managed servers
- Include examples: 'mcpm inspect filesystem', 'mcpm inspect time'
- Show 'mcpm ls' command to discover available servers
- Add yellow border panel to make the choice clear and actionable

Example flow:
  mcpm inspect              # Shows options, prompts for confirmation
  mcpm inspect filesystem   # Direct inspection of specific server
