Add support for NeTEx Lighting element for Quay

[solita-topip]

Is your feature request related to a problem? Please describe.
NeTEx (Nordic) supports a Lighting element on Quay, but it is not currently supported on Tiamat + Abzu.

Goal / high level use-case
Enable support for Quay Lighting facility: persist in database, expose via GraphQL API, handle correctly on NeTEx import/export, and make it editable in Abzu UI.

Describe the solution you'd like

Backend (Tiamat)

1. Override @Transient annotation for Quay.Lighting
2. Create new DB column in quay table
3. Add lighting field to GraphQL API for Quay
4. Ensure correct handling on NeTEx import/export

Frontend (Abzu)

1. Add multiselect option under "Facilities" tab (similar to "Walking surface indicators")

Describe alternatives you've considered

I took the liberty of correcting lightning to lighting.
