Hide named checkbox

[davidsbailey]

Description

finishes LP-752

By default, each level in a stage appears as a bubble in a row without any special name:

If you want to give a lesson or group of lessons a name, you do so via named or progression:

script overview page:

script edit gui page:

when using the named checkbox, you also have to go into each level and specify the display_name there: https://github.com/code-dot-org/code-dot-org/blob/24eb3b0b9731c75a818cd9714b76fd91ce63b8d8/dashboard/config/scripts/levels/CSD%20U2L04%20TFMD_2019.level#L9-L8

Because you can accomplish the same goal more easily by just specifying a progression name on the one level you want to name, this PR deprecates the named checkbox by hiding it in the edit UI unless it was already in use:

it also reorders the checkboxes, but that shouldn't matter because no one is using this UI yet.

Testing story

verified end-to-end manually (see screenshots). updated existing unit test to verify absence of named checkbox. existing tests cover presence of named checkbox.

I wonder about the tooltip text. Is it worth adding in the "named" tooltip that this deprecated and progression should be used? It might be confusing to see a reference to the "named" checkbox in the progression tooltip when there isn't a named checkbox. Otherwise, LGTM!

Great idea! I removed the mention of the named checkbox from the progression tooltip, and if people follow the suggestion in the named tooltip when they see it then they should be good.
