feat(launcher): implement auto-collapse coordinator and overhauled configuration UI

- Introduced 'Launcher_Cfg_Section' with 3-way state support (collapsed, auto, pinned).
- Implemented 'handle_section_expand' coordinator in 'launcher_cfg.svelte' for single-active-section behavior.
- Overhauled all configuration sub-components to participate in the auto-collapse logic.
- Updated 'ae_events_stores.ts' with new persistent section states.
- Synchronized 'launcher_cfg_template.svelte' with the new pattern for future extensions.
