Restructure profile pages

[ajparsons]

We have a bit of a mixed structure on the MP profile page at the moment. We roughly have a “short content” summary pages with multiple boxes, and related views for longer content ‘recent votes’ and ‘Voting record’.

The problem with this is we have two navigation bars - one for within the page, and one linking out to the other views. Where something to do with ‘votes’ appears three times.

I think we want in the long run to be cutting down this page until we just have the ‘profile’ content (with potentially some new language explaining the sections), But we can work in bits to get there - described in separate tickets.

Relates to #1712 as having a clear pattern on how we can add boxes/pages would be useful. (even if it’s just a simple pattern we can copy rather than a complicated approach).

Related tickets:

• Rebrand ‘voting records’ as ‘voting summary’ #1737
• Move ‘significant’ votes from profile page to be top element on voting summary page.  #1738
• Better summaries of contributions in debates #1740
• Create a new view for ‘register of interests’ on the top nav bar rather than the same page as the summary. #1739
