v0.13.0 - Add Consumption Sheets module

New module for tracking production consumption with lot scanning:
- Admin configuration for process types (AD WIP, etc.)
- Dynamic table creation per process
- Flexible header/detail field definitions with Excel cell mapping
- Duplicate detection with configurable key field
- Staff scanning interface with duplicate warnings (same session/cross session)
- Excel export using uploaded templates with multi-page support
- Template settings for rows per page and detail start row
