[FEATURE]: Show tool call arguments in TUI tool call permission request

Describe the enhancement you want to request

Tool call arguments were not always very apparent in tool call approval requests through the TUI. This causes issues, as there are times when the arguments of the tool call are important for the context of if they should be approved or not.

While this information was sometimes provided in-line of the chat for primary agents, I found the subagent tool calls were completely blind in this regard. Also, it is a better UX if the user is able to see it presented in the approval selection UI.

This issue might be a duplicate of existing issues. Please check:

• [FEATURE]: Display MCP Tool Parameters in Permission Dialog #12111: Display MCP Tool Parameters in Permission Dialog - addresses the same visibility concern but focuses on MCP tools. This feature request also notes that tool parameters should be shown in permission dialogs for better decision-making.

Feel free to ignore if this addresses different aspects of your specific case.
