This commit introduces a new `clearable` prop to the `Select` component, allowing users to easily reset its value.
When the `clearable` prop is set to true, a clear button (an 'X' icon) is displayed when an option is selected. Clicking this button resets the select input to its initial placeholder state and triggers an optional `onClear` callback.
To support this, the component's internal state management was refactored to control the input's value.
Additionally, the `AdminListFilters` component has been updated to:
- Utilize the new clearable select for the status filter.
- Consolidate multiple search fields (email, username, full_name) into a single generic "search" input.
- Add explicit "Reset" and "Apply" buttons for better filter management.
