Enable file upload/paste as a task in AGS. Enables tasks like

- Can you research and fact check the ideas in this screenshot?
- Summarize this file

Only text and images supported for now
Underneath, it constructs TextMessage and Multimodal messages as the
task.

This PR defines the missing `LLMCallEventMessage` class to resolve an
instantiation error that occurs when using custom messages (e.g., via
AgentStudio).

> _“i updated agentchat and agentcore and tried running the config from
agentstudio and it is now not running the agent and is throwing error
`TypeError: Can't instantiate abstract class LLMCallEventMessage with
abstract methods to_model_message, to_model_text, to_text`”_

The issue stems from `LLMCallEventMessage` being an abstract class that
lacks required methods from `BaseChatMessage`.
This PR implements the missing methods.

Since `LLMCallEventMessage` is intended for **logging/UI use only**, and
not to be sent to LLMs, the `to_model_message()` method raises
`NotImplementedError` by design.

## Authentication

This PR implements an experimental authentication feature to enable
personalized experiences (multiple users). Currently, only GitHub
authentication is supported. You can extend the base authentication
class to add support for other authentication methods.

By default authenticatio is disabled and only enabled when you pass in
the `--auth-config` argument when running the application.

### Enable GitHub Authentication

To enable GitHub authentication, create a `auth.yaml` file in your app
directory:

```yaml
type: github
jwt_secret: "your-secret-key"
token_expiry_minutes: 60
github:
  client_id: "your-github-client-id"
  client_secret: "your-github-client-secret"
  callback_url: "http://localhost:8081/api/auth/callback"
  scopes: ["user:email"]
```

Please see the documentation on [GitHub
OAuth](https://docs.github.com/en/apps/oauth-apps/building-oauth-apps/authenticating-to-the-rest-api-with-an-oauth-app)
for more details on obtaining the `client_id` and `client_secret`.

To pass in this configuration you can use the `--auth-config` argument
when running the application:

```bash
autogenstudio ui --auth-config /path/to/auth.yaml
```

Or set the environment variable:

```bash
export AUTOGENSTUDIO_AUTH_CONFIG="/path/to/auth.yaml"
```

```{note}
- Authentication is currently experimental and may change in future releases
- User data is stored in your configured database
- When enabled, all API endpoints require authentication except for the authentication endpoints
- WebSocket connections require the token to be passed as a query parameter (`?token=your-jwt-token`)

```

## Why are these changes needed?

Fix bug in AGS UI where frontend crashes because the default team config
is null

- update /teams endpoint to always return a default team if none is
found for the user
- update UI to check for team before rendering 
- also update run_id type to be autoincrement int (similar to team id)
instead of uuid. This helps side step the migration failed errors
related to UUID type when using an sqlite backend

## Why are these changes needed?

> Hey Victor, this is maybe a bug, but when a session is delete, runs
and messages for that session are not deleted, any reason why to keep
them?

@husseinmozannar 

The main fix is to add a pragma that ensures SQL lite enforces foreign
key constraints.
Also needed to update error messages for autoupgrade of databases. Also
adds a test for cascade deletes and for parts of teammanager

With this fix,

- Messages get deleted when the run is deleted 
- Runs get deleted when sessiosn are deleted 
- Sessions get deleted when a team is deleted

## Why are these changes needed?

This PR updates AGS to use the declarative config serialization native
to AgentChat.
The effect? You can build your teams/artifacts directly in python, run
`team.dump_component()` and immediately run it in AGS.

Some change details:

- Removes ComponentFactory. Instead TeamManager just loads team specs
directly using `Team.load_component`.
- Some fixes to the UI to simplify drag and drop experience.  
- Improve layout of nodes...
