Y24-433 - [BUG] AssetNotFound exception & AASM::InvalidTransition exception in Rails 7 upgrade.

[BenTopping]

Describe the bug
This work requires the rails 7 upgrades to be restored / readied. Currently the changes are not in develop or master and will need to be remade (which can be seen in previous PRs including ones linked below).

Rails 7 release (2.2.6) was yanked because it contained the below bugs. These can both be found in the samples extraction exception history (17-18/09/24) and linked to RT #810702. The reason these exceptions are grouped is because they both occurred after the rails 7 upgrade. In order to progress this repositories dependencies and upgrade to rails 7 these bugs will need to be addressed.

A Sprockets::Rails::Helper::AssetNotFound occurred in activities#update:

  The asset "" is not present in the asset pipeline.

  app/helpers/application_helper.rb:119:in `data_asset_display_for_tube'

An AASM::InvalidTransition occurred in steps#create:

  Event 'run' cannot transition from 'pending'. Failed callback(s): [:assets_compatible_with_step_type].
  app/models/activities/tasks.rb:15:in `block in create_step'

These errors occured after the rails 7 upgrade so it is likely to be caused by an unforseen dependency breaking change.

Identify the cause of this errors, fix the problem and add tests.
