[Bug]: urlpattern port matching fails for services on non-default ports

[ARCJ137442]

Summary

OpenAI-compatible providers on non-default ports (e.g. http://192.168.3.10:1234) cannot be reached — TouchAI rejects the URL as not allowed on the configured scope.

Steps to reproduce

1. Run a local LLM server (LM Studio, Ollama, vLLM) on a non-standard port, e.g. :1234
2. Add an OpenAI-compatible provider in TouchAI settings with URL http://192.168.3.10:1234
3. Click "Test Connection" or try to fetch models

Expected behavior

TouchAI should accept the URL and successfully connect to the OpenAI-compatible server.

Actual behavior

TouchAI shows:

url not allowed on the configured scope: http://192.168.3.10:1234/v1/models

Additionally, if the test passes the scope check, leaving API key empty causes:

OpenAI API key is missing. Pass it using the 'apiKey' parameter.

Affected area

• tauri

TouchAI version

1.2.0

Environment

Windows 11, LM Studio on LAN (192.168.3.10:1234), Qwen models

Logs, screenshots, or recordings

Error message: url not allowed on the configured scope: http://192.168.3.10:1234/v1/models

Root cause: capabilities/default.json uses http://** which urlpattern normalizes port to "" (empty string). A URL with explicit :1234 produces port() = "1234", which does not match "".
