🐛 fix(ui): prevent trailing dash clipping in cluster names on hover

[ANAMASGARD]

Root Cause

The NodeLabel component's card style has:

• overflow: 'hidden' - which clips content
• transform: scale(1.02) on hover - which scales the content up

When combined, the 2% scale increase caused text at the edges (especially trailing characters like -) to be clipped by the hidden overflow.

Fixes #2300

Solution

Changed the overflow property to be dynamic based on hover state:

overflow: isHovered ? 'visible' : 'hidden'

Hi @ANAMASGARD. Thanks for your PR.

I'm waiting for a kubestellar member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Pull request overview

This PR fixes a UI rendering issue in the topology NodeLabel where cluster names (notably trailing characters like -) were being clipped during the hover scale animation due to overflow: hidden on the card container.

Changes:

• Make the NodeLabel card container’s overflow switch to visible while hovered to avoid clipping during transform: scale(1.02).
• Minor formatting/indentation adjustment in the labels tooltip Chip styling block (no functional change).
