Expose per-agent provider in TUI settings model-picker

Status: pending

The TUI settings screen (src/ui/screens/settings/) lets you pick an agent's model but doesn't expose _souveraine.provider. An agent routed through z.ai can only be configured via hand-editing agent.json + DB.

What needs doing

• Add a provider field/picker in the settings UI (likely alongside the model picker in model_picker.rs or field_grid.rs)
• Populate options from ProviderRegistry's known provider names
• Write through to agent.json and database.sqlite3 config_json
