Fix options menu button height in side panel footer (#16107)

## Description
Fixed the height of the options menu button in the side panel footer to
be 24px instead of 32px, matching the height of other buttons in the
footer.

## Changes
- Added `size="small"` prop to the `Button` component in
`OptionsDropdownMenu.tsx`
- This ensures consistent button sizing across the side panel footer

## Before
The options menu button was 32px high (medium size), making it larger
than other footer buttons.

/>


## After
The options menu button is now 24px high (small size), consistent with
other side panel footer buttons.
