pht() for view and form elements

Summary:
actually just wanted to `pht()` the //Cancel// button.

includes `pht()`ed exceptions.

refrained from `pht()`-ing `phabricator_relative_date()` since I wasn't too sure about the effects.

Test Plan: visited all form elements that I remembered - looks reasonable
