Fix mitochondrial fraction value

[cosa65]

Background

Both the pipeline and the default value set in data ingest expect maxFraction to be a fraction while the UI should display a percentage instead.

As the ticket says, the permanent fix would entail modifying the maxFraction processingConfig property to be maxPercentage in all the relevant places, which includes: data ingest (default value), pipeline, api (validation), ui (because it now accounts for this disparity) and also all the processingConfigs in experiments in dynamodb.

Performing this right now is not ideal since we are now using many experiments across both staging and production, so we have decided to create a ticket to implement the permanent solution when we are able to create databases migrations automatically.

The ticket for this is here: https://biomage.atlassian.net/browse/BIOMAGE-797

Use the default value between 0 and 1 instead of 3.5 which breaks the plot.
