fix(types): clean type fixes across 92 files

Apply proper TypeScript type corrections without any unsafe casts:
- Fix unknown/never/{} types from decompilation
- Correct function signatures and parameter types
- Add missing type declarations and interfaces
- Fix Ink component prop types
- Update API client/provider type annotations

Test files with mock data casts are included as-is (acceptable pattern).
