AB#128968-use-user-context-fields

[GhaziAlibi]

Description

Adds support for user contextual fields in calculated fields.

This updates the calculated field parser and aggregation pipeline to accept expressions such as {{user.country}} and resolve them from the logged-in user's attributes. Missing user attribute values now resolve to empty strings. The resource mutation logic was also updated so these direct user expressions can be saved safely as calculated fields.
