Fix Lead List filtering and resolve Svelte 5 subscription crash

- Refactored Lead List to use direct observable subscription for better reactivity.
- Implemented in-memory 'Hard Guard' filter to ensure licensee selection is strictly enforced.
- Fixed 'TypeError: s.subscribe is not a function' by removing legacy $ prefix from resolved props.
- Resolved TypeScript typing errors in Lead Detail and Search components.
- Migrated Badge Search icons to Lucide.
