Merge Portfolio details into one view

[greghint]

A key part of the demo is to show buying stock increases Loyalty Level, and providing feedback affects sentiment. With the two tabs, it requires the user to buy/sell stock, then toggle over to see any change in Loyalty Level (or to see current sentiment before submitting new feedback).

I suggest you alter the design to move "User Details" to the top in 2 columns above the stock overview.

Specifically:

• 2 columns for details on top
• Table for portfolio underneath
• Add text for Sentiment next to icon (to show what API returns)
• For the message, put in same spot above portfolio table
