refactor(pres_mgmt): consistent layout, menu structure, and centering

- Add (pres_mgmt)/+layout.svelte with shared section wrapper (max-w-7xl mx-auto)
  so all child pages center correctly on wide viewports
- Strip per-page outer <section> tags from session, presenter, location pages;
  replace with inner <div max-w-7xl mx-auto> for detail constraint
- Restructure all page menus from flex-row to flex-col so nav bar occupies its
  own row and options/actions sit in a separate justified row below — prevents
  unwanted wrapping when nav is w-full
- Standardize Æ Core button visibility to edit_mode && manager_access across all
  menus; update button style to ae_btn_warning for visual distinction
- Add w-full + justify-between to ae_comp__events_menu_nav outer div
