fix(typescript): resolve ProfileService typing issues and eliminate any types

- Replace unsafe (error as any).config patterns with proper type guards
- Add hasConfigProperty() type guard for safe error property checking
- Add getConfigProperty() method for type-safe config extraction
- Eliminate @typescript-eslint/no-explicit-any violations

Problem: ProfileService had unsafe type casting with (error as any).config
that violated TypeScript type safety guidelines and caused linting errors.

Solution: Implement proper type guards following established patterns:
- hasConfigProperty() safely checks if error has config property
- getConfigProperty() extracts config without type casting
- Maintains exact same functionality while ensuring type safety

Files changed:
- src/services/ProfileService.ts: Replace any types with type guards

Testing: Linting passes, type-check passes, functionality preserved.
