Make generic type for services required

[ruscoder]

Example,
export async function getFHIRResources<R extends AidboxResource = never>
will force you to specify type

There is another better approach to define typings in a better way, for example, define a list of all resources in our typings (e.g., type ResourceTypeMap = { Patient: Patient, Practitioner: Practitioner, ...}) and then use T extends keyof ResourceTypeMap instead of T extends AidboxResource
