Reinstate headers
Make both nested tables(!) the full width of their column
Add heading
Replace table thing with simple statement of policy vote

Before the if conditional seemed to allow the display of an MP
comparison but I don't think that's used anywhere so I think it's safe
to remove that.
Do the really dumb thing and just copy and paste the party table

From the division detail page: https://github.com/openaustralia/publicwhip/blob/8640c7dc965f7dc101722019ab5e80a4db846543/website/tableoth.inc#L302-L409
Remove code that isn't used
Move queries closer to where they're used
Extract function and tidy up code formatting while we're at it
Replace copy and pasted code with function call
Enable tests for Policy => Details of votes page
Get page working with static text
Iterate over each division
Extract partial
Simplify method
Make page dynamic
Reset cycle so this partial can be reused and it matches PHP
