Subject: UI Bug/Inconsistency: Checklist Templates Missing from Template Center View

Description:

I am experiencing a critical visibility issue regarding Checklist Templates. While Task, List, and Folder templates appear in the "Template Center" gallery under "Created by Me," Checklist Templates do not appear there at all, even when all filters (Space, Folder, List, Task, etc.) are selected.

Steps to Reproduce:

Create a Checklist within a task and select "Save as Template."

Open the Template Center (Avatar -> Template Center -> Browse Templates).

Filter by "Created by Me."

Observe that the Checklist Template is missing from the gallery, making it impossible to manage or delete duplicates globally.

Expected Result:

Checklist Templates should have their own "Template Type" filter in the sidebar and appear as manageable cards in the Template Center alongside Task and List templates.

Actual Result:

Checklist Templates are "ghosted" from the main Library and can only be managed via a hidden "hover" menu inside an active task, leading to significant confusion and duplicate data.

Requested Fix:

Add "Checklist" as a visible Template Type in the Template Center sidebar so users can audit, rename, and delete them without needing to be inside an active task.
