Fix Vite circular dependency warning in select components

[dannon]

Description

The build produces a Vite warning about circular dependencies in the select UI components:

[WARN] [vite] Export "default" of module "src/components/ui/select/SelectContent.vue" was reexported through module "src/components/ui/select/index.ts" while both modules are dependencies of each other and will end up in different chunks by current Rollup settings.

Fix

Refactor the barrel exports in src/components/ui/select/index.ts to avoid the circular dependency, or restructure the component imports.

Priority

Low - doesn't break functionality, just a build warning.
