fix(leads): persist licensed auth across reloads; manage tab UX fixes

**Session persistence bug** — leads_loc_defaults was missing __version: 1.
store_versions.ts wipes ae_leads_loc when parsed.__version !== 1 (always true
when the field is absent), so every page reload cleared auth_exhibit_kv and
forced re-login. Adding __version: 1 to both the interface and defaults fixes
this for all auth types.

**Manage tab fixes:**
- Description: collapsed by default with ChevronDown/Up toggle — same pattern
  as session_view.svelte. Avoids long promo copy dominating the manage screen.
- Staff Passcode: removed duplicate green plain-text display for admins; the
  Element_ae_obj_field_editor already shows the value (was showing twice).
- Booth Identifier: replaced static read-only display with Element_ae_obj_field_editor
  so the booth code (exhibit.code) is editable inline.
