Revert "fix: remove duplicate buildings from the catalogue"

[KevinWu098]

Reverts #779

Reasoning:

    const validBuildingCodes = [...uniqueBuildingCodes].filter(
        (buildingCode) => buildingCatalogue[locationIds[buildingCode]] != null
    );

This is the reason why (from Map.tsx) ^^

The changes in #779, although confirmed to still work for all of the locations in map search, didn't take into account that location_ids.ts are the apparent source of truth for which ID in the list is the one we use. There may be more discrepancies still, but this is likely the source of the issue here

Originally noted in #784 ^^
