Add support for specifying a custom IP address for Ollama connection

[ALevkas]

Description

Currently, the program assumes that Ollama is running locally on port 11434 (e.g., localhost:11434).
However, in some setups, Ollama runs on a different machine within the same network or on a remote server.
It would be very helpful to have an option in the settings UI to manually specify an IP address (and optionally port) for Ollama instead of assuming localhost.

Proposed solution

Add a configuration field in the Ollama section allowing users to input a custom IP address and port (e.g., 192.168.1.100:11434).
Validate the input format and display an error if the connection cannot be established.
Fallback to default (localhost:11434) if no custom IP is provided.

Use case

This would enable users running Ollama remotely (e.g., on a dedicated local server or NAS) to connect without needing to proxy or mirror the port locally.

Example

Ollama host: 192.168.1.100
Port: 11434

Hello! I will work on this feature this week, it is one of the first to-do's I have :)

Thanks for the suggestion!

Hey! I added this feature. You can try it on the 1.0.1 release of StudyCraft!

Important thing: if you want to use Ollama cloud models, be sure to first start a chat with them. Otherwise they will not be exposed in Ollama's /api/tags endpoint. I also added a handy "Reload Models" button so that if you download a new model you don't have to close/open the Settings menu for it to appear.

Let me know if this works fine on your case for closing this issue :)
