When `allowed_domains` is configured on a web widget inbox, the server
responds with Content-Security-Policy: frame-ancestors <domains>, which
blocks the widget iframe in mobile app WebViews. This happens because
WebViews load content from file:// or null origins, which cannot match
any domain in the frame-ancestors directive.
This adds a per-inbox toggle — "Enable widget in mobile apps" — that
skips the frame-ancestors header when the request has no valid Origin
(i.e., it comes from a mobile WebView). Web browsers with a real origin
still get domain restrictions enforced as usual.

How to test
1. Go to Settings → Inboxes → (Web Widget) → Configuration
2. Set allowed_domains to a specific domain (e.g., *.example.com)
3. Try loading the widget in a mobile app WebView — it should be blocked
4. Enable "Enable widget in mobile apps" checkbox
5. Reload the widget in the WebView — it should now load successfully
6. Verify the widget on a website not in the allowed domains list is
still blocked

## Summary
- add a configurable MAXIMUM_FILE_UPLOAD_SIZE installation setting and
surface it through super admin and global config payloads
- apply the configurable limit to attachment validations and shared
upload helpers on dashboard and widget
- introduce a reusable helper with unit tests for parsing the limit and
extend attachment specs for configurability

We wanted to provide an option for users to specify the domains on which
they can show the website. The rest of the sites shouldn't see the
widget at all.
It's not possible generally through Origin because you can't get Origin
when loading via an iframe. What I've done is add frame ancestors for
the domains specified in allowed domains. I hope this solves most of the
problems.
This is added in a way that it won't affect existing widgets. Only If
they have configured allowed domains, it will start blocking. Otherwise,
it would follow the previous behavior without any changes.
This change supports called wild card domains as well. You can add a
comma‑separated list of domains, either wild card or regular domains.

To test, deploy to staging. Call the following API to update the
allowed_domains list.
```
URL: PATCH /api/v1/accounts/<account-id>/inboxes/<inbox-id>
Payload:
{
"channel": { "allowed_domains": "*.chatwoot.dev,chatwoot.com" }
}
```

At present, the websocket pubsub tokens are present at the contact objects in chatwoot. A better approach would be to have these tokens at the contact_inbox object instead. This helps chatwoot to deliver the websocket events targetted to the specific widget connection, stop contact events from leaking into other chat sessions from the same contact.
