Previously, when existing composer, the `#main-outlet` element padding was set to zero. This inline style would override any CSS set for that element, causing issues with the mobile footer nav.
The fix removes the inline padding style instead of setting it to zero. It also uses integers for the set values, and removes a duplicate style.

This feature can be enabled by choosing a destination for the
`shared drafts category` site setting.
* Staff members can create shared drafts, choosing a destination
category for the topic when it is published.
* Shared Drafts can be viewed in their category, or above the
topic list for the destination category where it will end up.
* When the shared draft is ready, it can be published to the
appropriate category by clicking a button on the topic view.
* When published, Drafts change their timestamps to the current
time, and any edits to the original post are removed.
