Add download option for pod logs

[A69SHUBHAM]

Summary

Currently, pod logs can be viewed within the dashboard, but there is no simple way to download them for offline inspection or sharing.

Proposal

Add a download action that allows users to save the currently displayed pod logs as a .log file.

Expected behavior

• A download button is available in the pod details/log view.
• Clicking the button downloads the currently displayed logs.
• The downloaded file uses the pod name as the filename when available.

Example:

my-pod.log

Benefits

• Easier log sharing during debugging.
• Better user experience when working with large log outputs.
• Complements future observability and log exploration features.
