Changes

Migrates identity page feature row to a typescript component. This allows us to:

• Get further reuse from feature row components
• Standardise the way we show features
• Makes the work to show feature deltas for a segment a lot more straight forward

How did you test this code?

• Test MV, segment and user overrides
• E2E cover a lot of this
