fix(test): replace any types in mock type definitions

eliminate any usage across TypeORM/Database mock types

 Replaced 23 any in types.ts and 5 any in index.ts with
 typed alternatives:
 - MockDataSource/MockRepository: generics + Record<string, unknown>
 - MockQueryBuilder: Record<string, unknown>
 - MockDatabaseService: unknown[]
 - createMockAxios: removed as any cast
