Post launch fixes: assets page

[kattylucy]

• Accrued fees should show as 0 rather than -0 if zero
• Sell button (same for Purchase/Finance/Repay) should be primary
• The margin near the heading, as well as the padding within the card, and the margin between the grey and white cards, is off compared to design

[kattylucy]

Only count the ongoing assets that still have a portfolio weighting, not all assets. it should be 6 ongoing assets

When you load the Assets tab, it now shortly shows the full list of assets, then flickers over to only the repaid assets. Would be great if this non-repaid assets would already be hidden on page load to remove this flicker.
