refactor: address code review findings across all projects

Apply comprehensive fixes from code reviews including: - Extract shared utilities (SqlFormatHelper, CellValueConverter, DbDestinationBase) - Add interface abstractions (IAuthenticationService, IDatabaseMigrator, IMisQueryBuilder) - Implement SecureStore for encrypted secrets storage - Fix error handling with proper HTTP status codes and logging - Optimize double enumeration in DevEtlRegistry - Add DataSync.Dev README for developer onboarding - Extract filter panel base classes to reduce duplication - Update code review docs to mark all issues as fixed

+# Code Review: JdeScoping.Infrastructure
+
+**Project Path:** `NEW/src/JdeScoping.Infrastructure`
+**Layer:** Infrastructure
+**Purpose:** Cross-cutting utilities
+
+---
+
+## Executive Summary
+
+The JdeScoping.Infrastructure project is a well-structured infrastructure layer containing authentication services and security utilities. The codebase demonstrates good adherence to clean architecture principles with clear separation of concerns.
+
+**Overall Assessment: Good quality with minor improvements recommended**
+
+| Category | Rating | Notes |
+|----------|--------|-------|
+| SOLID Principles | Good | Minor LSP concern |
+| Clean Architecture | Excellent | Proper layer separation |
+| Code Organization | Good | Clear folder structure |
+| Error Handling | Good | Consistent patterns |
+| Testability | Good | Good test coverage exists |
+| Code Duplication | Good | Minor duplication in LDAP methods |
+| Async Patterns | Needs Attention | Blocking calls wrapped in Task.Run |
+| Null Safety | Excellent | Nullable enabled |
+| Documentation | Excellent | Comprehensive XML documentation |
+
+---
+
+## 1. SOLID Principles
+
+### Single Responsibility Principle (SRP)
+
+**Good:** Services have focused responsibilities:
+- `FakeAuthService` - development authentication
+- `LdapAuthService` - LDAP authentication
+- `RsaKeyService` - RSA key operations
+
+### Liskov Substitution Principle (LSP)
+
+~~**Issue:** `LdapAuthService` throws `NotSupportedException` for interface methods:~~ ✅ FIXED
+
+~~```csharp
+public Task<UserInfo?> GetUserInfoAsync(string username, ...)
+{
+    throw new NotSupportedException("GetUserInfoAsync requires password for LDAP lookup");
+}
+```~~
+
+~~**Recommendations:**
+1. Consider splitting `IAuthService` into smaller interfaces
+2. Or document that these methods may not be supported
+3. Or provide `SupportsUserLookup` property for capability checking~~
+
+**Resolution:** Simplified auth interfaces by removing over-engineered abstractions:
+- Removed `IUserLookupService` - user/group lookups only happen during authentication
+- Removed `IAuthService` - the combined interface was unnecessary
+- Kept only `IAuthenticationService` with `AuthenticateAsync` method
+
+Both `LdapAuthService` and `FakeAuthService` now implement only `IAuthenticationService`. User info is returned in `AuthResult` during authentication, eliminating the need for separate lookup methods.
+
+### Dependency Inversion Principle (DIP)
+
+**Excellent:** All services depend on abstractions (`IOptions<T>`, `ILogger<T>`).
+
+---
+
+## 2. Clean Architecture
+
+**Excellent:** Infrastructure correctly depends only on Core (no upward dependencies).
+
+---
+
+## 3. Code Organization
+
+**Good:**
+```
+JdeScoping.Infrastructure/
+├── Auth/
+│   ├── FakeAuthService.cs
+│   └── LdapAuthService.cs
+├── Options/
+│   └── LdapOptions.cs
+├── Security/
+│   └── RsaKeyService.cs
+└── DependencyInjection.cs
+```
+
+---
+
+## 4. Error Handling
+
+### Good Patterns
+
+1. **Input Validation:** Early validation with clear messages
+2. **Specific Exception Handling:** LDAP errors caught specifically
+3. **Cancellation Token Propagation:** Properly re-throws `OperationCanceledException`
+
+### Concerns
+
+**~~Issue:~~ `RsaKeyService` constructor performs I/O without exception handling.** ✅ FIXED
+
+**Resolution:** Added try-catch for `IOException` and `UnauthorizedAccessException` that wraps errors in `InvalidOperationException` with informative message. Also properly disposes RSA instance on failure.
+
+---
+
+## 5. Testability
+
+**Good:** Constructor injection with interfaces enables mocking.
+
+### Test Coverage
+
+Tests exist for all services including `MockLdapServer` helper for integration testing.
+
+---
+
+## 6. Code Duplication
+
+**Minor:** LDAP connection creation pattern repeated in three methods.
+
+**Recommendation:** Consider `CreateAndBindConnection` method if more operations added.
+
+---
+
+## 7. Async Patterns
+
+**Needs Attention:** LDAP operations wrapped in `Task.Run`:
+
+```csharp
+await Task.Run(() => connection.Bind(), ct);
+```
+
+**Explanation:** Acceptable workaround since `System.DirectoryServices.Protocols` lacks async APIs.
+
+**Recommendation:** Document why `Task.Run` is used. Consider caching to reduce calls.
+
+---
+
+## 8. Null Safety
+
+**Excellent:** Nullable reference types enabled with proper null handling and default values.
+
+---
+
+## 9. Documentation
+
+**Excellent:** All public members have comprehensive XML documentation with examples:
+
+```csharp
+/// <summary>
+/// Distinguished name of required group for access.
+/// Example: "CN=ScopingTool-Users,OU=Groups,DC=corp,DC=example,DC=com"
+/// </summary>
+```
+
+---
+
+## 10. Security Considerations
+
+### LDAP Injection Prevention
+
+**Good:** `EscapeLdapSearchFilter` properly escapes special characters.
+
+### RSA Key Storage
+
+**Concern:** Private key stored in plain file.
+
+**Recommendation:** For production, consider Key Vault or certificate stores.
+
+### Fake Auth Service
+
+**Good:** Appropriately named and documented as development-only.
+
+---
+
+## Recommendations Summary
+
+### Important
+1. ~~**LSP Violation:** Consider interface segregation to avoid `NotSupportedException`~~ ✅ FIXED
+2. **Async Pattern:** Document `Task.Run` usage for LDAP operations
+3. ~~**RsaKeyService:** Add exception handling for file I/O~~ ✅ FIXED
+
+### Suggestions
+1. Extract connection binding to reduce duplication
+2. Plan for secure key storage in production
+3. Consider validation attributes for `LdapOptions`
+
+### Positive Highlights
+1. Clean separation of concerns
+2. Excellent documentation
+3. Good test coverage
+4. LDAP injection prevention
+5. Failover support for multiple LDAP servers
