Nathnael f28b6faf29 feat(operations-reporting): plan station targets per cargo category
The OCC report plans a station lane per cargo type — Nagad–Mojo container
and Nagad–Mojo fertilizer are separate numbers — but a target's identity
was period + metric + dimension + dimensionKey, so the two collided on
one slot. `cargo_category` is now part of the row and of the uniqueness
check; it stays null for cargo_category and container_class targets,
whose dimensionKey already carries the category.

The config grid showed raw codes (VOLUME_TONS, cargo_category, a yard
code). The list read now sends readable twins alongside the stored codes,
which stay exactly as they are because the reports join on them — the
same shape YardDistancesService uses. Labels resolve per dimension rather
than from one merged map: CONTAINER_EXPORT exists in both vocabularies
and reads differently in each, and merging them gave every cargo-category
row the container-class wording.

/**
* A station's plan is per station AND per cargo type, not per station.
*
* The OCC monthly report plans "NagadMojo multimodal container 122,010 t" and
* "NagadMojo fertilizer 18,000 t" as separate lines against the same station,
* which the single `dimension_key` column cannot express: a station-keyed target
* would apply the whole station's plan to each of its cargo types.
*
* `cargo_category` is nullable, so `cargo_category` and `container_class`
* targets are unaffected — they leave it null and stay keyed on
* `dimension_key` alone. The uniqueness index moves to include it, since
* (station, category) is now the slot.
