Description

Migrate shadcn/ui from Radix to Base UI.

Reasons:

1. Radix is no longer being developed.
2. Base UI is recommended as the default component library. Incidentally, I found the Base UI API to be superior, for example, in terms of handling the closing of Dialog windows and handling the indeterminate state of elements.
3. In the current configuration, Base UI and Radix were used simultaneously, which is certainly allowed, but having two libraries increases the cognitive load on developers and AI agents when writing code, since they have to think about the APIs of two component libraries at once; moreover, during migration, we can reduce the bundle size by removing Radix (and upon removing radix-ui, pnpm-lock.yaml was reduced by 1,250 lines by removing @radix-ui/* primitives).

Changes in the PR:

1. Migrate shadcn/ui from Radix to Base UI.
2. Fix TypeScript errors (due to the migration) and a few minor ESLint errors.
3. Update pnpm-lock.yaml for PNPM 11.
4. Add .editorconfig.
