Fix vehicle creation failing with null id

[rderewianko]

Fixes #202

When creating a vehicle, the client sends id: null in the request body. Drizzle's $defaultFn only fires when a value is undefined, not when it's explicitly null, so the UUID was never generated and SQLite threw a NOT NULL constraint error.

Fix: explicitly generate the UUID in addVehicle instead of relying on the schema default.

Hi, and thanks a lot for the work. You app looks very promising, I would love to use it for sure.
I'm afraid I'm encountering the same situation now :

Is there something I'm doing wrong ?
