[OPTIMISATION] Server sync dynamic data

[chrismclarke]

Details
When dynamic data is stored, a full row of data is stored locally which can contain a lot of information. This full row is then synced to the server as part of user backup/sync operations, resulting in large payloads (see related #2809)

Recommendations

See sub-issues

Further considerations
Profile restore actions will need to be handled carefully if partial states stored, as the data on the server could represent either minimal write layer as updated onto existing data, or a full row that was created by dynamic data service insert
