API keys now run as a user and inherit that user's module, operation, and client permissions. Drops per-key client scoping and removes existing keys (must be recreated). Adds an edit modal to change a key's user.
- Remove old client ID queries, these are now built into the API keys. If a key has access to all clients, a client ID can be provided in the query.
- Small fixes to assets URI lookup
- Add read endpoint for vendors
