Support for multiple HubSpot accounts / configurations

Problem/Motivation

Steps to reproduce

The current implementation only allows a single configuration tied to one Hubspot account.

Proposed resolution

In some scenarios—especially for agencies or multisite setups—there is a need to connect to different HubSpot accounts and collect forms separately for each. Currently, this isn’t possible out of the box.

To address this limitation, I’ve created a patch that extends the module’s functionality allowing forms to be retrieved and rendered from different HubSpot accounts from custom modules.

I’d love for the community to review this patch and consider including it in the module. Feedback, suggestions, and testing are very welcome!
