Feature: Update kdm health command to be interactive

[utkarsh232005]

🎯 Goal

Convert the kdm health command from static color-coded text output into a fully interactive health dashboard with live-updating progress bars, collapsible panels, and inline error inspection.

---

📌 Current Behavior

kdm health checks the health of workloads and outputs color-coded logs and details.

Options:

Flag	Description
-w, --watch	Run in watch mode to continuously refresh output
-i, --interval <seconds>	Refresh interval in seconds (default: 5)

Subcommands:

Subcommand	Description
kdm health all	Unified health check of both containers and pods
kdm health pods	Health checks for pods only
kdm health containers	Health checks for Docker containers only

Example usage:

kdm health all
kdm health pods -w
kdm health containers -w -i 2
