Function buildEnumFilter

buildEnumFilter(
field: string,
values: string | string[],
): { [key: string]: { in: string[] } }
Builds Prisma enum filter for matching against specific values.

This utility creates a Prisma where clause for filtering by specific enum values or a list of allowed values. It handles both single values and arrays of values, using Prisma's 'in' operator for multiple values.
Parameters
- field: string
  Database field name to apply the enum filter to
- values: string | string[]
  Single value or array of values to match
Returns { [key: string]: { in: string[] } }
Prisma where clause object with 'in' condition
Example
```
// Single language filter
const langFilter = buildEnumFilter('sourceLanguage', 'en');
// Returns: { sourceLanguage: { in: ['en'] } }
```
Example
```
// Multiple language filter
const multiLangFilter = buildEnumFilter('sourceLanguage', ['en', 'es', 'fr']);
// Returns: { sourceLanguage: { in: ['en', 'es', 'fr'] } }
```
Example
```
// Empty values returns empty object
const emptyFilter = buildEnumFilter('status', '');
// Returns: {}
```
