- Monthly actuals grid now filters actual_amount to entry_type='monthly_actual'
only, so other posted JEs in the same month don't bleed into the actuals UI
- Remove manual accounts.balance reversal from void() — the reversal JE's post()
call already handles balance updates, preventing double-decrement per void
- Date void reversal entries to the original entry's date (not today) so
historical monthly cash-flow periods stay accurate when actuals are re-edited
- Cash flow forecast now derives opening investment balances from investments
purchased before the forecast start date rather than using current-snapshot
totals, fixing historical months showing wrong investment balances
