[TASK] Migrate from Material Icons to Material Symbols (Rounded, Weight 600)

Description

We need to migrate our icon library from Material Icons to Material Symbols to stay up to date with Google’s latest design system and improve visual alignment with the Lara theme from PrimeNG.

Material Symbols share the same icon names as Material Icons, so the transition should be mostly seamless. However, we need to verify that no icons break or render incorrectly after the migration.

Configuration to apply:
• Style: Material Symbols
• Fill: Off
• Weight: 600
• Grade: 0
• Rounded: Yes

Acceptance Criteria

Acceptance Criteria
• Material Symbols library is installed and correctly configured.
• The configuration matches:
Fill: off
Style: Material Symbols
Style: Rounded
Weight: 600
Grade: 0
• All existing icons continue to render correctly with the new library.

Priority

None

Additional Context

Library Configuration:

Start by locating the existing Material Icons configuration and the code that supplies icon names. Check how the current icons are loaded and rendered, then verify the replacement uses the requested Rounded, weight 600, grade 0, fill-off settings and that existing icons still render correctly.
