feat(14-02): add LeadsSearch, rewire leads pages, surface tags in LeadDetail (CRM-08/09)

- New LeadsSearch.tsx: client-side instant filter across name/email/
  company/status/tags (mirrors CatalogSearch.tsx)
- page.tsx: fetch via getLeadsWithTags()/getLeadFieldOptions(), render
  LeadsSearch + CreateLeadModal, revalidate=0
- [id]/page.tsx: fetch getLeadsWithTags()/getLeadFieldOptions(), find
  lead by id, pass tags/tagOptions to LeadDetail
- LeadDetail.tsx: add OptionMultiSelect for lead tags in the "Profilo"
  card, wired to addLeadTag/removeLeadTag/renameLeadTag with error display
