feat(code): fix padding on command center new task UI (#1927)

## Problem

the new task UI in the command center, on small screen sizes, has no padding

<!-- Who is this for and what problem does it solve? -->

<!-- Closes #ISSUE_ID -->

## Changes

- adds padding
- [lazy-fix, but good regardless imo] drops the "Effort"/"Reasoning" label from dropdown

<!-- What did you change and why? -->

<!-- If there are frontend changes, include screenshots. -->
