fix(dirt): improve dialog type safety and error logging

Addresses critical PR review issues in NewApplicationsDialogComponent:

**Type Safety:**
- Replace unsafe type casting `(this as any).dialogRef` with proper DialogRef injection
- Inject DialogRef<boolean | undefined> using Angular's inject() function
- Ensures type safety and prevents runtime errors from missing dialogRef

**Error Handling:**
- Add LogService to dialog component
- Log errors with "[NewApplicationsDialog]" for debugging
- Maintain user-facing error toast while adding server-side logging

**Impact:**
- Eliminates TypeScript safety bypasses
- Improves production debugging capabilities
- Follows Angular dependency injection best practices
