RI-7766 Remove old color override for the selected state of the keys badges

[valkirilov]

What

Make the badges for the keys in the browser, to remain readable once the key is selected (on light theme).

Note: This component needs refactoring, because there are plenty of SASS styles that should be dropped.

Testing

1. Open Redis Insight and go to the Databases tab
2. Open existing database connection, or establish a new one
3. Make sure you have keys in this database (execute SET hello world in the CLI)
4. Click on the key in the left panel on the Browser page

Observe the colors of the badge when the key is selected. It should remain readable.

Before	After

---

Note

Removes the .nodeSelected .nodeContent * color override so selected key badges keep readable colors while retaining active background and border.

• UI/Styles:
  • In redisinsight/ui/src/pages/browser/components/virtual-tree/components/Node/styles.module.scss, remove nodeSelected .nodeContent * { color: var(--euiColorFullShade) !important; } to avoid forcing text color on selected items.
  • Selection styling (border-left-color, background-color) remains unchanged.
