front: implement macro editor OP import

[emersion]

Import operational points into NGE.

Closes #7737
Closes #7739
Depends on #8006 (in other words, please ignore the first few commits, they belong to that other PR)

TODO:

• Handle non-UIC path items
• Prettify node coords
• Pagination
• Handle OP secondary code?
• Adjust coords for large number of nodes (try with France infra test cases, e.g. Paris-Lyon-Grenoble)
• Find a more suitable location for the new files?
• Check if rtk-query requests need to be unsubscribed
• The import process should only kick in when the macro tab is selected
• Passthrough UICs/trigrams that we don't find in infra
