chore: update copy for deposit to unknown app

[kathaypacific]

Description

It may be unavoidable that some dapps that we do not know about create transactions that are parsed as deposits / withdraws etc. The "unknown dapp" message reads a little bit like an error (and was flagged as such at bugapalooza, context) so this PR updates the copy. Open for other suggestions too.

Network scalability

If a new NetworkId and/or Network are added in the future, the changes in this PR will:

• Continue to work without code changes, OR trigger a compilation error (guaranteeing we find it when a new network is added)
