Also show the declaration of field in processing

[vaibhavantil2]

Is your feature request related to a problem? Please describe.
Currently, Privado only shows the set part in the Processing instances but for me to understand if it is actually the right field I would need to see the declaration of the field from where that personal data was tagged.

Describe the solution you'd like
A possible solution could be to show processing similar to data flows where the source becomes the declaration and the sink becomes the processing instance shown currently. One possible problem with this in UI could be if the same declaration is related to multiple processing instances, it could seem a lot like repetition so we can possibly consider smarter grouping.

Describe alternatives you've considered
Current alternative is to audit the code to go back and confirm the declaration.

Additional context
In the screenshot attached only one processing instance, it is easy to identify the processing by looking at code i.e. this.phoneNo all others require more context.
