feat: wire offer→project phases/tasks, redo Offerte tab, cleanup project tabs

- importOfferIntoProject(): materializes project phases/tasks from the assigned
  tier's services grouped by services.fase (merge-by-title, dedup tasks)
- assignOfferToProject: optional import_phases flag triggers the import
- getProjectFullDetail: projectOffers/availableMicros now include macro name +
  tier_letter (dropdown shows "Offerta — Tier X"); availableMicros filters
  non-archived macros
- OffersTab redone: shows macro + tier badge, "Importa fasi e task" checkbox
- removed project "Preventivo" tab + deleted QuoteTab.tsx (legacy quote_items)
- sidebar: Lead before Clienti
- no DB migration (reuses existing tables)
