FW Lite push entry changes to frontend

[hahn-kev]

this covers a couple things

• lexbox has a signalR hub which pushes sync notifications to clients
• fw lite listens to lexbox project change notifications, and triggers a sync for that project
• after a crdt sync, the updated entries are pushed to the frontend

todo

• improve responsiveness. Right now it takes a few seconds for clients to receive changes, that's when running locally, it will get worse over the internet.

LGTM. Again, lots of compiler warnings made this look larger than it actually was, so I opened #1042 to track getting rid of the ones that are truly safe to ignore. But this PR looks good.
