Workflow: Optional Encounter ID and Search By URL expansion

[vitorpamplona]

Two new features in the PR:

1. Enables the call to generate a care plan without an encounter.
2. Restructures FhirDal to support search by URL in any ResourceType (Previously, only Measure and Library were allowed).

The same test case covers both features.

IMPORTANT: All PRs must be linked to an issue (except for extremely trivial and straightforward changes).
