backend: change view attributes endpoint location

[teosarca]

What is the current behavior?

Current view attributes endpoint is /rest/api/documentView/{windowId}/{viewId}/{rowId}

What is the expected or desired behavior?

Change it to: /rest/api/documentView/{windowId}/{viewId}/{rowId}/attributes
i.e. we will append the "/attributes" because we want to avoid overlapping with other endpoints will be based on current view row (/rest/api/documentView/{windowId}/{viewId}/{rowId}).

Which are the steps to reproduce?

Browse some HUs in https://w101.metasfresh.com:8443/window/540189
Mind the attributes related endpoint calls.

Note to IT: quick regression on all things which have fields and typeahead/dropdowns is needed

• window
• grid view
• address editor
• ASI editor
• process parameters
• HU Editor -> Attributes
