FIX: Enhance capacitor creation with name parameter and refresh IDs

[Samuelopez-ansys]

Description

This pull request introduces a minor fix to how IDs are assigned to circuit primitives and updates a related test to ensure correct behavior when creating capacitors with custom names.

Improvements to ID assignment:

• Updated the assignment of the id attribute in refresh_all_ids in primitives_circuit.py to handle cases where the name is not a number, assigning the value directly instead of converting to int. This makes the code more robust to non-numeric IDs.

It was found running this example:
