Show withdrawn deferred ect to schools

Ticket here

Context

This PR covers updates to the school-facing UI when an ECT’s latest training period at the school has been withdrawn or deferred by a lead provider via the API.

Previously, these states were not surfaced consistently across the ECT list and individual ECT details pages. This PR ensures withdrawn and deferred training statuses are displayed with the correct messaging, actions, and priority whilst leaving the underlying ECT at school period unchanged.

Changes proposed in this pull request

• Updated components to derive withdrawn and deferred states from the latest training period at the school, rather than from ECT-level attributes
• Added explicit handling for withdrawn vs deferred training periods in:
  • ECT list card components
  • ECT profile summary components
  • Training details components
• Added conditional rendering to:
  • show withdrawn-specific warning copy, status tags and CTAs only when the latest training period is withdrawn,
  • retain standard training summary rows for deferred training periods.
• Implemented precedence rules so that:
  • 'withdrawn' and 'deferred' training statuses override 'mentor required',
  • existing 'leaving school' and 'exempt' logic continues to take priority over withdrawn/deferred
• Ensured lead provider and delivery partner details are:
  • hidden for withdrawn training periods
  • preserved for deferred training periods

I think we could just name this status. training is redundant as this is a TrainingPeriod. school is also not relevant because the TrainingPeriod is linked to the ect/mentor_at_school_period, so it's not varying in this instance. It's also missing a test.

Yep that's fair. I originally went with school_training_status because we’ve got a couple of 'status' concepts floating around (participant/induction/training-period etc) and this one is specifically 'what schools should see'. Happy to rename to something like status_for_school ... we use training_status elsewhere

[thenapking]

OK, I understand your concern here. status_for_school doesn't really communicate the purpose of this as the naming suggests it's more to do with the view - what the school sees - but that might not be clear in the context. training_period.training_status is just a repetition, though if we can't think of anything better we can do that. I can see training_status used in the readme for example.

Thanks for the tests. They are fine obvs.

I think this is sound, and meets the ACs, but needs a little clean-up in places.
