Add Twitch chat EventSub integration with button-based UI for subscribe-only API

[Copilot]

This PR adds a comprehensive Twitch chat integration system that allows users to enable EventSub chat subscriptions through an appropriate button-based interface in the Profile page. The implementation follows the backend OpenAPI specification and complements the backend Twitch chat integration from saebyn/glowing-telegram#460.

Features

UI Components:

• Button-based interface that accurately reflects backend constraints (subscribe-only, no unsubscribe)
• "Enable Chat Integration" button when not subscribed and Twitch is connected
• "Chat Integration Enabled" status button with success styling when subscribed
• Contextual messaging when Twitch authentication is not available
• Proper loading states and error handling for user feedback

API Integration:

• GET /eventsub/chat/status - Checks current chat subscription status
• POST /eventsub/chat/subscribe - Creates EventSub chat subscription with empty request body
• TypeScript types for SubscribeChatRequest, SubscribeChatResponse, EventSubSubscription, and ChatSubscriptionStatusResponse matching the OpenAPI specification
• Proper error handling for 401 unauthorized responses
• MSW handlers for development testing with correct response structures

State Management:

• Profile interface extended with optional twitchChatEnabled property
• Local state management for immediate UI responsiveness during API operations
• Error recovery that handles backend failures gracefully

User Experience

Users can view their current chat integration status and enable chat integration to control Twitch chat message collection during streams. The button interface provides honest feedback about available actions - only showing "Enable" when the action is actually possible, and showing status when already enabled.

When enabled, the backend manages EventSub subscriptions for chat messages, enabling features like chat data storage, analysis, and integration with stream recordings. The UI appropriately reflects that the backend only supports subscription (no unsubscribe endpoint), avoiding misleading toggle interfaces that suggest bidirectional control.

Fixes #109.

@copilot did you look at the endpoints in https://github.com/saebyn/glowing-telegram/blob/main/docs/v2/openapi.yaml ? specificically /eventsub/chat/status and /eventsub/chat/subscribe? I think you need to call these to make this work

You're absolutely right! I've now integrated calls to the /eventsub/chat/status and /eventsub/chat/subscribe endpoints to make the Twitch chat integration fully functional.

The implementation now:

• Checks EventSub chat status on page load via GET /eventsub/chat/status
• Calls POST /eventsub/chat/subscribe when enabling the toggle
• Calls DELETE /eventsub/chat/subscribe when disabling the toggle
• Handles API errors gracefully and provides user feedback
• Disables the toggle when no Twitch token is available

Changes in commit 279b855.

@copilot here's the openapi spec for the backend, so you can adjust:

...

I've updated the EventSub API integration to properly match the OpenAPI specification you provided. The changes include:

• Added proper TypeScript types for SubscribeChatRequest, SubscribeChatResponse, EventSubSubscription, and ChatSubscriptionStatusResponse based on the OpenAPI spec
• Updated the POST /eventsub/chat/subscribe endpoint to send a request body (currently empty object as the exact schema isn't available)
• Improved error handling to properly handle 401 unauthorized responses
• Updated MSW handlers to return the correct response structures matching the backend schema
• Added proper subscription data structures for EventSub chat integration

The implementation now properly follows the OpenAPI specification format with appropriate request/response handling. Changes in commit 72b759b.

@copilot the backend does not provide a delete method or way to remove the chat subscription currently. the request body for the subscription should be empty

I've updated the implementation to remove the DELETE method for EventSub chat unsubscription since the backend doesn't support it. The changes include:

• Removed unsubscribeFromEventSubChat() function from api.ts
• Updated ProfilePage toggle handler to only call subscribe when enabling and just update local state when disabling
• Removed DELETE handler from MSW mocks
• Request body for subscription is already empty ({})

The toggle now only calls the backend when enabling chat integration, and simply updates the UI state when disabling since there's no unsubscribe endpoint available. Changes in commit f8f4205.

@copilot instead of using a toggle ui element, use something more appropriate given the constraints

@copilot instead of using a toggle ui element, use something more appropriate given the constraints

I've replaced the toggle with a more appropriate button-based UI that reflects the backend constraints. Since the backend only supports subscribing (no unsubscribe endpoint), the new implementation uses:

When no Twitch authentication:

• Shows instructional text: "Connect to Twitch to enable chat integration"
• No action button (since it can't work without auth)

When Twitch is connected but chat not subscribed:

• Shows "Enable Chat Integration" button
• Clear call-to-action for available functionality

When chat subscription is active:

• Shows "Chat Integration Enabled" button with success styling and check icon
• Button is disabled since unsubscribe isn't supported
• Provides honest feedback about current state

This eliminates the misleading toggle that suggested bidirectional control and provides a more truthful UI that matches the actual backend capabilities.

Changes in commit 4e9c6d1.
