Feature - Wake On LAN

[bitbound]

This PR adds Wake-on-LAN feature. It can be triggered for an individual device or a device group. The server will look for devices that are eligible to wake the offline device by matching either the device group or the public IP address.

Other Changes:

• Removed some old code.
• Renamed AgentHubSessionCache (formerly "Service").
• Added new overload to ToastService.
• Reduced the initial load of server logs to 1 day.
• Changed IMessenger registration from Singleton to Scoped.
  • Scoped is essentially per-connection singleton in Blazor Server.
  • Singleton was causing events to trigger in other tabs.
• Expanded test data.
• Changed authorization behavior so devices that aren't in groups are no longer considered "public".
  • This was a workaround for a legacy issue that no longer exists.

Thank you for your contribution to the Remotely project. It is required that contributors assign copyright to Immense Networks so we retain full ownership of the project.

This makes it easier for other entities to use the software because they only have to deal with one copyright holder. It also gives me assurance that we'll be able to make decisions in the future without gathering and consulting all contributors.

While this may seem odd, many open source maintainers practice this. Here are a couple well-known examples:

• Free Software Foundation: http://www.gnu.org/licenses/why-assign.html
• Microsoft: https://cla.opensource.microsoft.com/

I lost power while fixing the unit tests for this. I'll take care of it tomorrow.
