User story: As a Commons editor, I want consistency in button placement, so that I can think about more important things than where each button is located depending on what I'm editing..
**We have this:**
Currently with Depicts statements on File Page in Edit mode, both the Edit and Publish changes/Cancel buttons are in the top right corner. For Captions, only the Edit button is in the top right corner, and Publish changes/Cancel is in the lower right. The initial reasoning for having it at the bottom for captions was that there could often be many captions and the idea was to have the publish button at the bottom so user wouldn't have to scroll back up. Because of continued padding adjustments, the scrolling should be reduced and we should aim for consistency between panels.
**We want this:**
For Captions Edit/Publish/Cancel buttons to be consistent with Depicts. With testing, we can start with that and see how common it is for people to add enough values where having to scroll back up to save is an annoyance.
**Acceptance Criteria: **
 The Captions Edit/Publish/Cancel buttons are in the upper right corner.
