refactor: clean up $getActiveIdentity method and fix null handling

- Remove excessive debug logging statements
- Fix critical bug: cast activeDid as string | null instead of string
- Refactor to use early return pattern, reducing nesting from 4 to 2-3 levels
- Eliminate redundant logic and improve code readability
- Maintain all original functionality while simplifying flow
- Fix null activeDid case that was breaking app initialization
