style(launcher): Phase 3 — FA→Lucide icon migration across all launcher files

Replaces all FontAwesome <span class="fas/fab fa-*"> with Lucide Svelte
components across 20 launcher files. launcher_cfg_section.svelte icon prop
changed from FA string to AnyComponent (svelte:component for dynamic render).
Dynamic file-extension icon now uses ae_util.file_extension_icon_lucide().
Fixes class: directives on components (invalid in Svelte 5) → ternary class.
Removes title prop from Lucide components → wrapping <span title="...">.
