Rename debounceStrategy to currentDebounceStrategy for clarity

The POSSearchable protocol had two confusingly named properties:
- debounceStrategy: The currently active strategy
- searchDebounceStrategy: The strategy that will be used for searches

Renamed debounceStrategy → currentDebounceStrategy to make the
distinction clear: currentDebounceStrategy reflects what's active
right now, while searchDebounceStrategy reflects what will be used
when searching.

This improves code readability without changing any behavior.
