Overhaul Models tab UX: action feedback, post-training flow, guided navigation

- Lift modelsTab state into Zustand store so actions can navigate tabs
- Add toast notifications + auto-tab-switch to all 10 model actions
  (train, configure SFT/alignment, distill, fine-tune, quantize, eval, deploy, open-source)
- Add actionable toast buttons with navigation (e.g., "Go to Families" on training complete)
- Fix post-training config: remove 50% deadline, show until pretraining completes,
  always-visible warning prompt outside card expand, engine reminder at 75%
- PostTrainingConfig now hides already-configured sections independently
- Add tab badges: pulsing dot for active jobs, count for undeployed models, warning for no deployment
- Replace empty states with actionable buttons guiding next steps
- Stage bars show "(skip)" in warning color for unconfigured SFT/Alignment stages
