Smooth out some UI/UX issues in Harbormaster
Summary:
Ref T8096. Fixes a few bugs and glitches.
- Set build completion time when handling a message.
- Format duration information in a more human-readable way.
- Use a table for build variables.
- Fix up container PHIDs on diffs (a touch hacky, should be OK for now though).
Test Plan: Browsed around the UI.
