Enable ability to have beacon-only mode for a space, no billboard

[limbofeather]

This is for users who would like to collect traffic data from the metaverse, without necessarily placing a billboard there.

Will need to update docs on a way to fetch data from the beacon analytics that are being collected for other consumers, such as Lighthouse or Hyperfy.

Is this not technically already done by way of the separate beacon package in the repo?

EDIT: Nvm, forgot spaces creators without billboards have no spaceId set to query

Closing for now
