FOSFA-283: Resolve issue with case tokens not resolved via webform

[olayiwola-compucorp]

Context

Following the resolution of the issue with case tokens not being resolved in PR #789, it was noted that the solution implemented did not encompass scenarios where the email is triggered outside the CiviCRM context, such as cases created through webform submissions. This PR addresses this gap by refining the logic for evaluating case roles and custom field tokens. Regardless of how the case is created and the email is triggered, the tokens' values are now appropriately evaluated.

Template

Below is the template containing a case token, case custom field token, and case role token.

Case ID {case.id}

Argo card {case_cf.custom_175}

Role {case_roles.client_display_name}

Before

Previously, only the case token was resolved.

After

Now, all token categories are resolved appropriately.
