Standardize Exhibit Leads module: Rich text support and naming alignment

- Integrated TipTap rich text editor for Booth Descriptions and Exhibitor Notes.
- Implemented strip_html utility for clean search/preview of rich text fields.
- Renamed exhibit loading functions to follow load_ae_obj_id__event_exhibit* pattern.
- Hardened property processors with 'undefined' string guards and automatic reload triggers.
- Resolved type mismatches and naming inconsistencies across the Leads module.
- Verified zero-error state via svelte-check.
