Add product search with autocomplete, filters, and sort

- Header: search button opening a command-palette dialog with debounced product suggestions, a term chip, and View All - Command: shadcn-shaped primitives built on the project's own Dialog so no cmdk/radix dependency is introduced - /search: results grid with item count, sort (relevance, price asc/desc), and cursor-based load more - Filters: driven by the API's productFilters facets — colour swatches, labelled lists with counts, and a price range — round-tripped through each facet's raw input string so no filter shape is hardcoded Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_016jWbNNJLksC1QG8z8845FX
