A SETTING entity opened in the Harmonia application shell renders in a small box, not full height

[NicoleNG18]

Describe the bug

A SETTING entity opened from the application shell's Settings panel (/services/web/application/) renders in a short, cramped box at the top of the content pane — a few hundred px tall, with an internal scrollbar on the list and a large empty area below — instead of filling the pane. This is persistent for apps that publish only SETTING entities, where the Settings panel is the only way to reach the data. A PRIMARY (domain) entity fills the pane correctly.

To Reproduce

1. Publish an app whose entities are all SETTING entities
2. Open the application shell at /services/web/application/.
3. In the sidebar footer, click Settings.
4. Select one of the app's SETTING entities in the left list.
5. See the entity's list/manage view render in a short box at the top of the detail pane (≈3 rows + an internal scrollbar), with most of the pane empty below.

Expected behavior

A SETTING entity opened from the Settings panel should fill the detail pane to full height — the same way a PRIMARY entity fills the content area — with no short box, no premature internal scrollbar, and no large empty region below, including for settings-only apps.
