feat: move studio projects to a /studio/projects child page

Extract the studio-category post grid out of page-studio.php into its own
page-projects.php template. Created the WP page 'Projects' (ID 3876) as a child
of Studio (1198), so it resolves at /studio/projects/. page-studio.php now ends
after the tab section — clearing it for the rework.

(The WP page itself lives in the DB, not git.)
