Quick design edits for Assets detail page

[sonam-jo]

We will do a bigger redesign of the Assets page. But for the release coming up, want to make the following quick cosmetic changes on the Assets detail page:

• Remove the numbers in the diamond shape from the individual asset detail pages
• Change the style of Ongoing to be the same as Open for investments in the Overview page (yellow background with dark yellow text)
• Change the colour of Download background from Charcoal to light grey
• Change the graph line from Blue to Yellow (in line with the Overview chart)
• Remove the grey boxing and blue font for the Type in Transaction history. Instead match the font to the rest of the table but in Bold.
