refactor: remove services/api exclusion from ty type checking

Removed the blanket exclusion of `services/api/**/*.py` from ty type
checking. Performance testing showed only a 26ms difference (0.125s vs
0.151s), making the "performance" justification invalid. Now all services
and packages are type-checked consistently.
