♿ chore: Bump Click UI to v0.2.0-rc.4, Fix Dialog A11y Warnings

[punkbit]

Summary

Bumps @clickhouse/click-ui from 0.0.252-test.7 to 0.2.0-rc.4 and resolves all Radix Dialog console warnings.

Click UI changes (rc.2–rc.4):

• Dialog.Title now uses RadixDialog.Title primitive — suppresses DialogContent requires a DialogTitle warning
• Hidden RadixDialog.Description rendered when no description prop is provided — suppresses Missing Description warning

Admin panel changes:

• Deduplicate @radix-ui/react-dialog via Vite resolve.dedupe and overrides — cmdk bundled its own copy with a separate Radix context, preventing our fixes from working
• Add hidden DialogTitle + DialogDescription to all Command.Dialog usages (CommandMenu, ScopeSelector) since cmdk doesn't render these Radix primitives internally

Change Type

• Bug fix (non-breaking change which fixes an issue)

Testing

• All dialogs render correctly (edit role, edit group, create role, create group, edit capabilities, settings, confirm save, import YAML, profile value, delete profile value, profile indicator, user detail)
• Command menu (Cmd+K) opens without console warnings
• Scope selector (base config switcher) opens without console warnings
• No DialogContent requires a DialogTitle warnings in console
• No Missing Description warnings in console
• No visual regressions — dialogs look identical to before

Closes #13
