7e53eff642 Fix the async flow with the Router 
It had sequential async calls with complexity O(n), with a variety of redundant
calls. There was also a constant of... 4? 5? for each item. Now, the total
sequence depth is just 3-4.

669b8b776b Work on testing the Router 
Completes the `Executed` enum in the router. Adds an `Escape` struct. Both are
needed for testing purposes.

Documents the gas constants in intent and reasoning.

Adds modernized tests around key rotation and the escape hatch.

Also updates the rest of the codebase which had accumulated errors.

6508957cbc Make a proper nonReentrant modifier 
A transaction couldn't call execute twice within a single TX prior. Now, it
can.

Also adds a bit more context to the escape hatch events/errors.

554c5778e4 Don't track deployment block in the Router 
This technically has a TOCTOU where we sync an Epoch's metadata (signifying we
did sync to that point), then check if the Router was deployed, yet at that
very moment the node resets to genesis. By ensuring the Router is deployed, we
avoid this (and don't need to track the deployment block in-contract).

Also uses a JoinSet to sync the 32 blocks in parallel.

7e4c59a0a3 Have the Router track its deployment block 
Prevents a consensus split where some nodes would drop transfers if their node
didn't think the Router was deployed, and some would handle them.

bc1bbf9951 Set a fixed fee transferred to the caller for publication 
Avoids the risk of the gas used by the contract exceeding the gas presumed to
be used (causing an insolvency).

8ea5acbacb Update the Router smart contract to pay fees to the caller 
The caller is paid a fixed fee per unit of gas spent. That arguably
incentivizes the publisher to raise the gas used by internal calls, yet this
doesn't effect the user UX as they'll have flatly paid the worst-case fee
already. It does pose a risk where callers are arguably incentivized to cause
transaction failures which consume all the gas, not just increased gas, yet:

1) Modern smart contracts don't error by consuming all the gas
2) This is presumably infeasible
3) Even if it was feasible, the gas fees gained presumably exceed the gas fees
   spent causing the failure

The benefit to only paying the callers for the gas used, not the gas alotted,
is it allows Serai to build up a buffer. While this should be minor, a few
cents on every transaction at best, if we ever do have any costs slip through
the cracks, it ideally is sufficient to handle those.
