[Media Router WebUI] Make blue color styling darker.

Currently, paper blue 500 and white do not have enough contrast.

This change replaces all usages of paper blue 500 with 700, which is the next darkest paper blue color that passes the accessibility audit. This fixes the AX_COLOR_01 warnings related to the blue color.
