refactor(schema): update API schemas for libsql and mount

- Replaced `createSchema.pick` with `z.object` for `apiFindOneLibsql` and `apiFindMountByApplicationId` to enforce stricter validation.
- Ensured `libsqlId`, `serviceType`, and `serviceId` are required strings with minimum length constraints.
