feat(mileage): add brand multi-select filter and customer fuzzy search

- Add brand multi-select filter (BatchMultiSelect) with 17 brand options
- Replace customer select with SearchableSelect for fuzzy search
- Server-side: add brand to vehicle-info SQL, cache, filters, and monitoring
- Customer filter now uses case-insensitive includes match on server side
- Add brand column to fullscreen table header and body
- Mobile-adaptive: compact inputs, constrained widths, scrollable dropdowns
- Bump version to 1.1.8
