Chore(1-3894): update old/new name display + remove strategy type names (#10305)

This PR updates how we show old/new strategy/segment names in change
requests, and also removes the name of the strategy type from the
change.

For the old/new names: instead of showing them stacked vertically, we
show them side by side (old name first, then new name).

Compare before:

/>


with after:

<img width="974" alt="image"
src="https://github.com/user-attachments/assets/d0f85264-b055-4c44-b985-f992f09d8dab"
/>


Only affects the new components (legacy CR view is untouched). If we get
negative feedback while rolling it out because the strat type name is
missing, we can always add it back.
