* feat: Handle database connection errors with 500
- If database goes away while unleash is running, unleash now stays
running, but all api endpoints will return 500.
- This includes our health endpoint, which allows k8s or similar
orchestrators to decide what should be done, rather than Unleash
terminating unexpectedly
This sets up the typescript compiler.
Allowing gradual migration to typescript.
