Coach lineup polish, referee level/position delete, feature-flag nav gating, per-job pause

- Coach line-up screen: more breathing room above the sheet, brighter event
  subtitle, and the "Schedule" button now matches the date input's height.
- Positions and referee levels can now be deleted from Settings (blocked with
  a friendly message if still in use on a roster/referee profile/inheritance
  chain).
- The Evaluations nav placeholder is now gated on the formbuilder flag, same
  as Forms itself, since the design reuses formbuilder underneath.
- Control panel: each scheduled platform job can now be paused/resumed
  individually (features.models.JobToggle), independent of the platform-wide
  Maintenance lock.
