v1.3.0 - Launch Search and Filters

1. Added a search box matching missions, rockets, providers, orbits, and launch pads.
2. Added multi-word search with a short debounce delay to avoid filtering on every keystroke.
3. Added status filter chips for All, Go, TBC, and TBD.
4. Added a provider dropdown generated automatically from launch data, including launch counts.
5. Added an empty state for unmatched searches with a Clear Filters button.
6. Refactored the filtering logic around a shared filter state for cleaner list rendering.
