Adds http://127.0.0.1:* and ws://127.0.0.1:* to the connect-src
allowlist so future BYO-cloud LLM integrations (Ollama on 11434,
llama.cpp server on 8080, LM Studio on 1234, etc.) can fetch(...)
without tripping the CSP.
Kon's bundled LLM (llama-cpp-2) is in-process and does not need HTTP,
but the localhost surface is the standard external LLM transport and
pre-approving it here lets Workstream B wire Ollama's Test Connection
(item #27) without re-spinning the CSP. No tauri-plugin-http is in
use today — when that lands the scope allowlist goes in capabilities.
Matches the pain pattern from Vibe #438 (Tauri scope blocking
127.0.0.1 LLM endpoints).
