feat(04-02): admin projects list + client detail project cards

- NavBar: add Progetti (/admin/projects) and Impostazioni links
- ProjectRow: project table row with €/h calc (accepted_total / tracked hours)
- /admin/projects: table listing all projects with value, payments, timer, €/h
- /admin/projects/new: create form with client select + ?client_id pre-selection
- project-actions: createProject, archiveProject, unarchiveProject, updateProjectAcceptedTotal
- /admin/clients/[id]: rewritten to show project cards grid instead of tabbed workspace
- getAllClientsWithPayments: add projectBrands[] and ltv (sum of project accepted_totals)
- ClientRow: show project brand names under client name, LTV column replaces Totale
