Some maniphest / aphront form UI tweaks

Summary:
Just a few random things I wanted to tweak...

- Maniphest homepage tasks box has less padding so it vertically aligns with other "stuff" boxes
- Made form <h1> have more padding

Test Plan:
- Looked at Maniphest on the homepage -- looks good!
- Looked at Maniphest Task List
- " Batch Edit
- Looked at a view other form places like Herald rules and Repository edit - looks good
