Webapp: Dashboard analytics, integrations, and dev tools

The web app now has a proper dashboard so you can see what is happening at a glance, plus the beginning of an integrations system.

What's new

• An analytics dashboard with conversation activity, status breakdown, and a peak timing heatmap.
• Auto-refresh every 60 seconds with a visible countdown.
• Integrations management in settings for connecting external tools.
• Organization settings with logo upload and team member context in the sidebar.
• A developer toolbar for debugging and monitoring your SupportWire setup.
