feat: supplier modal wizard, pipeline delete, sidebar cleanup

- Replace two-tab supplier selector with two-step wizard (method select → suppliers → summary)
- Add per-item channel picker (Email / WhatsApp / Both) in By Item mode
- Add confirmation summary step before submitting By Item supplier assignments
- Add type-to-confirm delete on pipeline list rows
- Redirect purchase.requests.index to pipeline (same data, single entry point)
- Remove Purchase Requests from sidebar nav
- Add edit-request-modal, supplier-invite-list components
- Add address coordinates migration for settings_locations
