CRITICAL ISSUES: Database management service with major problems

WARNING: This commit contains code with significant issues that need immediate attention:

1. Type Safety Issues:
   - Unused import ZulipAccountsService causing compilation warnings
   - Implicit 'any' type in formatZulipAccount method parameter
   - Type inconsistencies in service injections

2. Service Integration Problems:
   - Inconsistent service interface usage
   - Missing proper type definitions for injected services
   - Potential runtime errors due to type mismatches

3. Code Quality Issues:
   - Violation of TypeScript strict mode requirements
   - Inconsistent error handling patterns
   - Missing proper interface implementations

 Files affected:
   - src/business/admin/database_management.service.ts (main issue)
   - Multiple test files and service implementations
   - Configuration and documentation updates

 Next steps required:
   1. Fix TypeScript compilation errors
   2. Implement proper type safety
   3. Resolve service injection inconsistencies
   4. Add comprehensive error handling
   5. Update tests to match new implementations

 Impact: High - affects admin functionality and system stability
 Priority: Urgent - requires immediate review and fixes
