fix(ui): Integrate webhooks panel into status panel

The webhooks panel was appearing separately from the status panel.
Now it's properly nested inside the status-panel div:

- Moved webhooks-section inside status-panel in HTML
- Updated CSS so nested webhooks looks like a subsection (no double borders)
- Simplified JS toggle logic - webhooks shows/hides automatically with status panel
- Admin users see webhooks inside status panel, collapsed by default
