Auto-assign projects to first round, auto-filter on close, pipeline UX consolidation

- New projects (admin create, CSV import, public form) auto-assign to program's
  first round (by sortOrder) when no round is specified
- Closing a FILTERING round auto-starts filtering job (configurable via
  autoFilterOnClose setting, defaults to true)
- Add SUBMISSION_RECEIVED notification type for confirming submissions
- Replace separate List/Pipeline toggle with integrated pipeline view below
  the sortable round list
- Add autoFilterOnClose toggle to filtering round type settings UI
