feat(ui): simplify CLIProxy page UX with dedicated Add Account dialog

- Remove redundant "Create Variant" button (Quick Setup is more comprehensive)
- Add AddAccountDialog component for per-provider account addition
- Keep "Quick Setup" for full variant creation wizard
- Keep "Add Account" per-row for adding accounts only
