Embed UI server

[jlegrone]

What changed?

Embeds the new Temporal UI server and static assets.

Why?

Closes #22

How did you test it?

go run ./cmd/temporalite start

Potential risks

• Binary size went from 76.6 to 99.4 MB. We might want to conditionally compile static assets into the binary in the future.
• There's a higher chance of port conflicts on 8080, which seems to be pretty commonly used in other areas of the Temporal ecosystem. In order to mitigate this, Temporalite defaults the web UI port to the frontend-service port + 1000.
• Importing temporal server and ui server packages in the same module also emits duplicate protobuf registration error logs. This could introduce issues if the protos drift between upstream modules, but I think it should be safe enough to merge this for now and fix the conflicts upstream.
