feat: add model selector UI to chat - #1633
Conversation
Add a model selector to the chat input area, letting users pick a model directly from chat instead of going through settings. Adds i18n translations for the selector across all supported locales. Co-Authored-By: JunyongParkDev <shewco3@gmail.com> Signed-off-by: daewoongoh <dw.oh@samsung.com> Signed-off-by: JunyongParkDev <jun94.park@samsung.com>
Filter the chat model selector's model list through the organization allowlist so it matches ModelPicker in settings, and keep the trigger visible while a dynamic provider's models are still loading. Signed-off-by: daewoongoh <daeungoh@gmail.com>
The unsupported-provider fallback could flash briefly for a dynamic provider whose router-models query was still loading but whose selected-model resolution had already finished. Gate both the fallback and the loading label on routerModels.isLoading as well.

Cover the loading-to-loaded transition.
This test stops while useRouterModels is loading. It does not prove that newly returned models update and enable the selector.
Update the mock, rerender the component, and assert that the loading label disappears and the returned models become selectable. This case detects the survived dependency-array mutation at ModelSelector.tsx Line 84.
As per path instructions, tests require “cleanup and deterministic async behavior.”

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Separate provider support from model availability.
isSupported becomes false when the organization allowlist removes every model. Line 188 then labels the supported provider as unsupported and directs the user to Settings, where the same allowlist still applies.
A router-model failure can enter the same branch after loading stops. Track provider capability, query failure, and an empty filtered list as separate states. Use the unsupported fallback only when the provider has no model-selection capability.

Use a native, named button for the search clear control.
When searchValue.length > 0, the span is the only clear action. Its onClick supports pointer input, but the span is not focusable or keyboard-activatable and does not expose a named control to assistive technology. Replace it with a native button or the existing IconButton, using type="button" and a localized accessible name for “Clear search.” Add that translation key to the common catalogs; common:ui.clear is not defined.

Address CodeRabbit review on PR Zoo-Code-Org#1633: an org allowlist that filters out every model (or a settled router-model query with zero results) was incorrectly treated the same as a provider with no model-selection capability, showing the unsupported/Settings fallback instead of a disabled trigger. isProviderSupported now only reflects whether the provider is dynamic or backed by a static model list; add test coverage for the allowlist-empties-everything case and fix the existing loading-to-loaded test's expectations to match.
