[IMP] account,*: Improve bank statements/payments workflow

- Create journal entries as soon as bank/cash statement lines are created, temporary booked on a suspense account set on the journal.
- Simplify the management of "blue" lines in the reconciliation widget. A "blue" line is now a journal item using a temporary liquidity account (outstanding payment/receipt accounts, set on the journal).
- Adapt and simplify the bank reconciliation report.
- Remove the bank reconciliation threshold date. The reconciliation report will show the not already reconciled journal entries using a liquidity account and the not already reconciled journal entries using a temporary liquidity account. Without accounting, an account.payment will involve directly the liquidity account and then, will be considered as a statement line directly.
- Remove the post_at bank reconciliation feature. The "paid" state will be set on the invoices only if reconciled with a journal entry involving the journal's liquidity account.
    With invoicing, the payment will do that so the "in_payment" state should never be shown up.
    With accounting, only the statement lines have the power to move an invoice to the "paid" state.
- Fix various corner cases about the management of multi-currency in bank statement lines.
- Fix the conversion dates in multi-currency: Since the bank/cash is always used on the statement lines, it will use always the real "bank" date instead of the fictive payment one.
- Ensure the 'reconcile' method will raise an error if the involved moves are not posted.
