🐛 fix: topic renaming input focus issue in context menu (lobehub#11323)

Fixes LOBE-2838

This commit resolves the issue where the input field wasn't properly focused when renaming topics through the context menu.

Changes:
- Created FocusableInput component that ensures input focus using queueMicrotask
- Replaced autoFocus prop with proper ref-based focus management
- Simplified onBlur handler logic
- Removed duplicate toggleEditing call from handleUpdate

The queueMicrotask approach ensures the focus happens after the Popover has fully rendered and positioned itself.
