Eliminate need for ingest checks targeting unsupported and privileged transactions

### Problem

We would prefer not to do work at ingest for unsupported or privileged transactions.

### Solution

Add appropriate minimal fees for all transaction types so they can be assigned to throttle buckets and go through the standard throttle check at ingest.

### Alternatives

_No response_

The issue names no files, tests, or entry points. Start by locating ingest handling for unsupported and privileged transactions, then trace transaction fee assignment and throttle buckets. Done means every transaction type receives an appropriate minimal fee and uses the standard ingest throttle check without separate ingest work.
