Hide the "Expand to Full Page" button on Email and Calendar pages (#8615)

### Overview
This pull request addresses issue #8612 by ensuring the "Expand to Full
Page" button does not appear on the Email and Calendar pages in the
right drawer.

### Changes Made
- Added conditions in the `RightDrawerTopBar` component to prevent the
`RightDrawerTopBarExpandButton` from rendering on:
  - Email pages (`RightDrawerPages.ViewEmailThread`)
  - Calendar pages (`RightDrawerPages.ViewCalendarEvent`)
- Verified that the button still renders correctly on other pages, such
as Record pages.

### Testing
Since I couldn't run the project locally, I was unable to confirm the
changes in a running environment. However, the logic has been carefully
updated to ensure the button is conditionally hidden based on the
current `rightDrawerPage` state.

### Additional Notes
Please let me know if further adjustments are needed or if there are any
issues during testing. Thank you for reviewing this PR!
