[Improvement] After enabling Kerberos, some icons in the web interface part through the Knox proxy cannot be displayed.

### What would you like to be improved?

gravitino 1.3.0

Hive、doris icon display normally， why？

### How should we improve?

Can all these icons be uniformly implemented using inline SVG?

Start by reproducing the missing icons in the Gravitino 1.3.0 web interface when accessed through the Knox proxy, using the attached screenshot as the expected symptom. Trace how the web interface loads its icons and determine which icons fail; done means the affected icons display correctly through Knox and existing interface behavior remains intact.
