redesign layout and expand to full SCM coverage

- Replace MatOne-clone sidebar with distinct blue navy sidebar design
- Lighter blue color palette (#5699DA) for better readability
- Remove app icon/logo, use text 'SCM' branding
- Fix sidebar active tab highlighting (only current page, not entire group)
- Fix duplicated title/search/button inside overflow-x-auto containers
- Restructure all list pages: filters before table, table outside flex

Add 20 new pages to cover missing requirements from SCM spec:
- Purchase Requisition (list, create, approval queue)
- PO 3-Way Matching with mismatch detail view
- PO Amendment workflow
- Supplier Performance scorecards, contacts, blacklist
- Returns/RMA workflow and ATP check
- Lot/Batch and Serial number tracking
- ABC Analysis, Pick List generation
- Freight Cost comparison, Shipping Documents
- Scenario Planning
- Notification Center with preferences
- System Integrations registry
- Custom Report Builder

Add documentation:
- docs/BP-SCM-ENGLISH.md — full business process documentation
- docs/BP-SCM-INDONESIA.md — versi Bahasa Indonesia
- docs/DIFFERENCES-ENGLISH.md — SCM vs MatOne MMS comparison
- docs/DIFFERENCES-INDONESIA.md — perbandingan SCM vs MatOne
