Phase 2 tweaks: admin tenant creation, unit delete, frequency, UI overhaul

- Admin panel: create tenants with org + first user, manage org status
  (active/suspended/archived), contract number and plan level fields
- Units: delete with invoice check, assessment group dropdown binding
- Assessment groups: frequency field (monthly/quarterly/annual) with
  income calculations normalized to monthly equivalents
- Sidebar: grouped nav sections (Financials, Assessments, Transactions,
  Planning, Reports, Admin), renamed Chart of Accounts to Accounts
- Header: replaced text with SVG logo
- Capital projects: Kanban as default view, table-only PDF export,
  Future category (beyond 5-year plan)
- Auth: block login for suspended/archived organizations
