Remove unnecessary layout calls from api controllers

These were left over from the refactoring of the controllers into api and non-api versions.

Rename the notes#mine action to index

Use bootstrap text-muted in place of custom deemphasze class

This avoids changing anything related to forms, since they will be
switched over to bootstrap separately.

Remove some extraneous css

The trace part is actually removing html, but I thought it was CSS
when I first noticed the blank space on the page.

Rework the users#show page to avoid custom column css

This uses bootstrap instead, ensuring the map shows before the
text on small screens, but to the right of it on md+ widths. The
height of the map also changes at this breakpoint instead of being
based on the menu width (body.small).

The account edit page was also changed to match the content_map
changes, and a full width map is now used. This can be changed, if
required, using bootstrap breakpoints but I like it as it is.
