🔧 Improve type safety in utils and tests

Replace 'any' with 'unknown' for better type safety

In hyper-light-card.test.ts:
- Update type assertions from 'as any' to 'as unknown'

In utils.ts:
- Modify log function parameters from 'any[]' to 'unknown[]'
- Add explicit return type 'void' to log functions
