feat(pres_mgmt): automate Session POC loading and enhance field editor UX

- Updated Element_ae_obj_field_editor_new.svelte with on_open callback support.
- Improved Select field UX in the editor with an inline loading spinner when options are empty.
- Streamlined session_view.svelte by using on_open to trigger person record loading automatically.
- Removed redundant manual 'Select Person' button in favor of automated lazy-loading.
