feat: adds dashboard census-feature parity across beacon, history, state networks

[mrferris]

Glados currently only gathers and displays census data for the history network. This PR:

• turns on state and beacon networks on glados's trin instance
• runs cartographer instances for state and beacon networks to gather census data
• adds a selector to the UI that filters and displays census data by network: history, state, or beacon, while filtering via an http param ?network= on the backend.

Bonus: continues the migration toward raw SQL and simplifies the calls for readability and maintenance purposes.

Implements #293 for census data.

Note that all audit data will still show history, which is a bit awkward (history audit data displayed next to beacon/state census data) but it will toggle audit data per network in the next PR.

Looks very good. I did find a bug! But it is only a 1 line difference to fix it!

This PR doesn't appear to update audit data depending on the selector, but as I said on discord we can always do that in the next PR, This PR already makes a lot of progress and is very helpful.

LGTM!

We already talked about this on the call, but I'll just leave it for posterity:

Next time you move a big chunk of code (say >hundred lines) from one place to another, would you mind doing it in a separate refactor commit? I find it much harder to review when there is a move & change at the same time: I can't use the diff to see what changed from the previous implementation. I ended up doing it myself here, which made it so much easier to review the meaningful changes in routes.rs.
