Disruptions - merge duplicate rail lines

[sam-wmca]

Epic: Find rail disruptions

---

Story details

As a

train user

I need to

See whether my line is affected by a disruption

So that

I can plan ahead and avoid disruption

---

Acceptance criteria

• [ ] Affected lines are decoupled from train companies
• [ ] Affected line only appears once in the list

---

This is a fix for manual rail disruptions. Currently, an affected line appears more than once. This is because the train companies affected cause the line to appear for each TOC.

Reference design is in Figma.
