admin 2fd311c8a2 Opening balances post to GL; unify all reports on the general ledger
- Opening balances now post a single "Opening Balances" journal entry to the GL
  (migration applied to prod), scoped to managed companies (imported-GL
  associations already carry theirs). Triggers on opening_balances /
  opening_balances_setup keep it in sync; Ashley Manor backfilled.
- Balance Sheet: read balances from the GL only (drop the separate opening add,
  which also double-counted imported companies).
- Trial Balance: compute balances from journal_entry_lines as of the report date
  (was accounts.balance).
- General Ledger report: read from journal_entry_lines (was transactions); opening
  rolls in from the GL.

All four reports now share one source. Verified Ashley Manor TB balances
(debits = credits = $90,073.23) with opening cash (BOA +$47,304.31) flowing through.

-- Post opening balances (accounting.opening_balances) to the general ledger as a
-- single "Opening Balances" journal entry, so they flow into every GL-based
-- report (Trial Balance, General Ledger, P&L, Balance Sheet) from one source.
--
-- Scoped by accounting.gl_managed(): only companies whose GL we generate (no
-- imported/foreign journal entries). Imported-GL companies (e.g. Bridgewater,
-- Bent Oak) already carry their opening balances inside the imported GL, so we
-- must NOT post theirs again. Keyed external_source='acmacc_opening',
-- external_id=company_id (one entry per company) — idempotent.
