Stability: Atomic creation of entities + authorization policies

[techsmyth]

Description

Currently is the creation of an entity fails, then there are often partial entities left over - causing both orphaned data and instability in the server.

Goal

Creation of entities should be done in memory, with only a single save at the end.

Hypothesis

Having atomic creation of entities will

• improve production server stability
• reduce data without the proper relations set
• improve developer effectiveness (less resetting of the database)

Must have scope

• Atomic creation of profile server#4102
• Atomic creation of Callout Contribution server#4103
• Atomic creation of Callout server#4104
• Atomic creation of Space server#4105
• Authorization policy updates to be done in-memory and with a single save per boundary entity. Note: a space is a boundary, in that when saving a space it does not cascade to the subspaces in there.
• [Spike] Upgrade to latest Typeorm server#4106

Stakeholders

Development
QA

Design

To be build up from lower level entities.
Spike can go last to derisk the rest of the work.
