Pull request overview

This PR adds a feature to save and restore the open/close state of accordion sections (options, detailed settings, etc.) in the baserCMS admin panel. The state is persisted per plugin+controller path using localStorage, so accordion sections remain in the same open/close state across page reloads.

Changes:

• Added getAccordionStorageKey(), loadAccordionState(), and saveAccordionState() helper functions to manage accordion state in localStorage, scoped by URL path segments.
• Added DOM-ready initialization code to restore accordion states from localStorage on page load.
• Updated the accordion click handler to persist state changes to localStorage and added a guard for missing data-bca-target.

startup は、defer 前提で読み込んでいるので、 $(function() { は、なくてもいいです
