Accounting platform: remove Zoho, unify reports, board access, vendor sharing

- Remove the Zoho Books integration (edge functions, sync libs, settings,
  reports/overview, banking links, fees tab, import dialog); preserve fee
  rules as a standalone FeesTab and the COA accounting_system classification.
- Financial Overview/Reports (staff + board) render the Accounting dashboard
  and reports; board reports mirror the rich Accounting Reports.
- New Reserve Fund Schedule report + an is_reserve flag on accounts.
- Unify all report exports to a branded format (logo + centered header +
  footer): shared ReportSheet (on-screen) and reportHeader (PDF). Budget vs
  Actuals and Bank Reconciliation PDFs now match the reference layout.
- Render financial reports inline (no preview pop-up).
- Budget Management mirrors Accounting Budgeting (staff-accessible) with SPA
  navigation; editable bills in the Accounting Bills page.
- Negative opening balances flow through to the GL and reports (allow negative
  input; keep non-zero on save; signed CSV import).
- Upload a per-account trial balance via CSV on Opening Balances.
- Board members: read-only RLS access to their association's accounting ledger;
  editable board-members panel on the association page; share vendor contacts
  with the board (toggle + directory section).
