Fix un-bound HTML attributes for gh-trim-focus-input

no issue
- updates `gh-trim-focus-input` to extend from `gh-input`/`one-way-input` to get the auto-binding attribute behaviour for passed-in HTML attributes
- renames `focus` property to `shouldFocus` so that we're not overriding default DOM functions
- fixes signin page issues with missing placeholders and no autofocus
