fix: use supported model presets in companion setup

[Telli]

The companion setup dropdown used stale preset IDs and omitted ollama-agentic. Its two-way selection binding cleared that valid preset, causing setup to fall back to the non-tool ollama-general profile and leaving local chat unable to select a tool-capable model.

Populate the dropdown from the same LocalModelPresetCatalog used by setup. This exposes supported presets and removes IDs that the CLI cannot resolve.

Validation: a headless Avalonia regression checks that the real window binding retains and saves ollama-agentic and every offered ID resolves. A desktop integration smoke using the updated companion and the released NativeAOT gateway/CLI passed setup, websocket chat through a local provider fixture, stop/restart/reconnect, corrupt-config recovery, and owned-gateway shutdown on desktop exit.
