fix(faucet): missing background and favicon routes

[Mirko-von-Leipzig]

Closes #671.

Created #673 to create tests for this.

---

I've deployed this to devnet and confirmed that

• both background and favicon load as expected, and
• no console errors

Did require clearing my cache first.

Looks good! Thank you! Question: should this go into main?

If we care to make a new release with it, then main probably.

If we care to make a new release with it, then main probably.

Maybe we release just the faucet crate? And for a change like this, we may even skip tagging a release.

I'll rebase to main.

Its a bit awkward with the formal deployment, options:

1. We use Deploy from the main branch - no release required. But this will currently redeploy everything. Would have to add an option to only deploy the faucet.
2. We manually deploy...
   1. using the faucet debian package - but this requires a github release to build it
   2. by manually building on the instance

(2ii) is the easiest and probably also the safest - but not popular with devops of course :D

eh - seems like all of these are a bit of a hassle for just adding a background image. let's just keep things as they are now.
