feat: replace PrimeVue AutoComplete with SearchAutocomplete in ManagerDialog (#9645)

## Summary

Replace legacy PrimeVue `AutoCompletePlus` with a new
`SearchAutocomplete` component built on Reka UI, matching the
`SearchInput` design system.

## Changes

- **What**: Add `SearchAutocomplete` component extending `SearchInput`
with dropdown suggestions, IME composition handling, and generic typed
`optionLabel` support. Replace `AutoCompletePlus` usage in
`ManagerDialog`.
- **Dependencies**: None (uses existing Reka UI Combobox primitives)

## Review Focus

- `SearchAutocomplete` feature parity with the replaced
`AutoCompletePlus` (suggestions, option selection, IME handling)
- Dropdown styling and positioning via Reka UI `ComboboxContent`
