feat: multi-tenant company refactor (GNU-19) (#153)

* feat: multi-tenant company refactor (GNU-19) Introduce companies table, company_members, and user_preferences to support multiple companies per user. All data scoping changes from user_id to company_id across the entire codebase. Key changes: - Database migration: new tables, company_id on 40+ tables, backfill, RLS rewrite from user_id to company-member-based, updated RPCs - Types: Company, CompanyMember, CompanyRole, UserPreferences types; company_id added to all entity interfaces; companyId on all events - Engine: all 7 core functions take companyId; storno, period, year-end services updated; 16 report generators updated - Middleware: company context resolution (cookie → prefs → first company) - API routes: ~120 routes updated with requireCompanyId() - Frontend: CompanyProvider context, layout/dashboard/onboarding updated - Extensions: context factory, 9 extensions, all lib files updated - Tests: 1880 tests passing, all helpers updated with company_id defaults Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: add database migrations for multi-tenant company and team system (GNU-19) Adds company_invitations, company creation RPC, team_members, account deletion RPC, and teams table refactor migrations. Updates base multi-tenant migration with cascading FKs and onboarding_step column.

Refactors Supabase service client to be stateless, updates middleware for team-aware routing, extends CompanyContext with team/role fields, and updates extension service types to accept companyId. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor: thread company_id through business logic functions (GNU-19) Replaces user_id scoping with company_id across all lib modules: bookkeeping, documents, transactions, invoices, reconciliation, tax, deadlines, and import.
