fix(ollama-local): support custom host URL for remote Ollama servers (closes #578)

Add a shared resolveOllamaLocalHost() helper and wire it through the
executor, models/validate/test routes, so users can point ollama-local
at a remote Ollama instance instead of being locked to localhost:11434.

Also expose the host as an "Ollama Host URL" field in AddApiKeyModal
(empty = default localhost:11434), making the option reachable from the
dashboard without hand-editing db.json.
