resolve relative media URLs against the API base in react-openapi

- add resolveMediaUrl() in fields/utils.ts: prefixes /uploads/... and
  other relative paths with the configured baseApiUrl, leaves absolute
  http/data/blob URLs untouched
- use it for every image render: ListCellRenderer, DetailFieldRenderer,
  ImageField form preview, and FileUploadField preview/href (which
  hardcoded /uploads/<value>)
- drop the Expense-side resolveLogoUrl hack and logo pre-normalization;
  the Expenses page now renders logos through the same react-openapi
  path as the admin entity list
