feat(submissions): add experimental warning and confirmation dialog to submission form

- Replace inline warning with shared ExperimentalWarning component
- Add confirmation dialog before submission to acknowledge experimental phase
- Refactor submission handler to show dialog first, then process on confirmation
- Warn users that submissions won't be reviewed during experimentation phase
