Editing Chronic disease (section)

==Rationale==
As at June 2024 the health team are recording Chronic disease contract activity in Indici.

Because Aiga is still in use - and still acts as the key data source for referral and allocation data - it is necessary to merge and reconcile the two data sets.

The general workflow for this pipeline is to:
# Source a set of current Chronic disease clients from Aiga
# Push data set to S3<ref>Bucket <code>kpa-aiga</code>.</ref>
# Write data set to RDS<ref>Schema <code>aiga_staging</code>.</ref>
# Build reconciled patient cohort, and count activities for reporting.
