FAST3896: Sagemcom APi not supported

[MagnusErler]

Versions

Key	Value
Home Assistant version	2025.2.0
Integration version	0.3.6
Sagemcom F@st model	FAST3896
Sagemcom F@st firmware (optional)	FAST3896-15_TDC-RDK_82.2.16

Describe the bug

When adding the integration, it fails due to the absence of a valid router that supports the Sagemcom API. However, the router is listed among the supported models.

To Reproduce

Steps to reproduce the behaviour:

1. Add integration
2. Type in host: 192.168.01, username: admin, and password
3. Hit submit
4. Error: Your host does not support the Sagemcom API endpoint used by this integration. Make sure you have provided the correct host and that your router is supported.

Expected behaviour

The integration should except the router as valid

Screenshots

Additional context

I have previously used the integration with a different router. I have removed that router (unplugged and removed in HA) and am now trying with a newer model
