Y26-077 - Add Fail Slider for LRC PBMC Aliquot in Limber

[Stan1520]

Context
During the LRC PBMC workflow, users assess sample viability and total cell count when transitioning from the LRC PBMC Defrost PBS 08ml page to the LRC PBMC Aliquot page in Limber. Currently, users must manually check individual cell count files to determine which samples should fail or require dilution. This manual process is time-consuming, error-prone, and inefficient during a time-sensitive step. Introducing fail sliders with predefined thresholds would provide a quick visual check to identify samples that should fail or require manual dilution.

User story
As a user, I want fail sliders for viability and total cell count to appear on the LRC PBMC Aliquot page in Limber, so that I can quickly identify samples that should fail or require dilution without manually checking external cell count files.

Acceptance criteria

Consider if these features can be featured flagged to decouple testing and deployment.
To be considered successful the solution must allow:

• Add sliders / thresholds for cell count and viability onto the LRC PBMC Aliquot plate
• Remove sliders / thresholds for cell count and viability from the LRC PBMC Defrost PBS 08ml plate
• The default slider values must be set to 50% viability and 500,000 total cells/ml.
• The sliders should work as per the other plates in the pipeline that they are currently defined on.

Deployment notes

Add any details that should be noted when deploying this feature. For example, is a database migration needed, a specifc rake task or other script that needs to be run, a dependency on another application or service that needs to be released first etc?
These notes are intended to ensure the developers releasing the feature know what needs to be done.

Confirmed relevant plates with Abby:

Please do not define on the LRC PBMC Defrost PBS 08ml plate
Please do define on the LRC PBMC Aliquot plate

Confirmed cell count threshold:

It should be 650,000 total cells/ml for the Bank plate and 500,000 for all other steps however we will always check and we slide it around to check max concentration too so it is not the end of the world if it is off as default but it would be good as a reminder.

--> Concerning as the current config says 50,000 - would like to look into when this happened and what the potential impact might have been.
