Styling, review of systems label position

[edwinychoi]

Spacing tweaks to improve scanability:

• Moving "x of x positive" to the left, and then right aligning with the "positive" labels lines up the column heading with the "positive" labels for faster header-data connection.

• Keeping the gray/white horizontal rows alternating throughout, for general consistency with other tables within Flux Notes.

• Pushing "negative" labels farther to the left allows easier connection of RoS elements with its label, and well as reduce chances of misreading the label across columns (for example, "negative nausea").
