Description of Changes

• Introduced reusable UI design primitives (under app/src/components/)
• Moved reused sx props into global theme provider
• Updated existing components to use the new primitives and global theme styling.
• Applied a general visual facelift for improved consistency across layouts, spacing, typography, and interaction states.

Testing Notes

• The application should function normally.
• Verify key workflows (tickets, policies, data requests, uploads) operate as expected.
• Perform a general visual pass to ensure layout, spacing, buttons, tables, and dialogs render consistently.
