test: increase timeout for validate.test.ts to handle slow ts-node spawns in CI

The validate.test.ts spawns ts-node processes which can be slow, especially in CI.
- Increased jest.setTimeout to 30 seconds for the test suite
- Increased spawnSync timeout from 10s to 25s
- This fixes test failures in CI where the test took 27s to complete
