[WIP] Deserialization failure for Activities with embeded ports on MongoDB for Elsa >=3.3.0

[Copilot]

Thanks for assigning this issue to me. I'm starting to work on it and will keep this PR's description up to date as I form a plan and make progress.

Original issue description:

Description

Switch and HttpRequest activities with at least one non-default ports (and probably all activities with embeded ports) on version >= 3.3.0 crash the workflow execution when using MongoDb. When starting the workflow, in designer no progress is visible as if nothing happens, and looking at the network we can see that POST requests to elsa/api/activity-executions/report fail with following exception:

System.FormatException: An error occurred while deserializing the ActivityState property of class Elsa.Workflows.Runtime.Entities.ActivityExecutionRecord: An error occurred while deserializing the Activity property of class Elsa.Workflows.Activities.SwitchCase: Unable to determine actual type of object to deserialize for interface type Elsa.Workflows.IActivity.
 ---> System.FormatException: An error occurred while deserializing the Activity property of class Elsa.Workflows.Activities.SwitchCase: Unable to determine actual type of object to deserialize for interface type Elsa.Workflows.IActivity.
 ---> System.FormatException: Unable to determine actual type of object to deserialize for interface type Elsa.Workflows.IActivity.

Steps to Reproduce

1. Ensure that MognoDb is the persistance provider
2. Create new workflow in designer
3. Add Switch activity
4. Add one case to Switch activity with true as condition
5. Run workflow and wait for the crash

This is the whole workflow:

Environment

• Elsa Package Version: tried on every release above 3.3.0 (except for pre-releases)
• Operating System: Windows 11
• **MongoDB version **: tested on 5.0.6, 6.0.6 and 8.0.5

Fixes #6455.
