Not all together functional update of Lookup endpoint to support POST. Tentative steps to allow partial result return, by moving Catalyst error calls out of the Model layer.
Missing condition that makes the endpoint populate the result hash.
Update help config to include symbol lookup POST. Replace ID copy-paste description with symbol description.
Alter Symbol endpoint action type and argument consumption.
Fix error response behaviour and allow symbol POST requests.
Add hint to response behaviour when some user data is invalid.
Test cases for Lookup POST, along with supporting methods.
Introducing an POST message limiter role. Individual endpoints can define a post_message_size key in the config so that overly large messages will be rejected before processing.
Update and configure other existing POST endpoints.
