This PR adds an option to include scheduled transactions in mmCheckingPanel, as proposed in #6860.

Implementation

• Declare struct Fused_Transaction::Data derived from Model_Checking::Data, which represents either a transaction or a single execution of a scheduled transaction. It contains the additional fields m_bdid and m_repeat_num. For a transaction, m_bdid and m_repeat_num are set to 0. For an execution of a scheduled transaction, m_bdid is the BDID of the original scheduled transaction, TRANSID is set to 0, m_repeat_num is the repetition number (starting from 1), TRANSDATE is the date of execution (it may be different than the TRANSDATE of the original scheduled transaction), and all other data fields are as if the scheduled transaction has been executed.

• Declare struct Fused_Transaction::Full_Data derived from Model_Checking::Full_Data, with the additional fields m_bdid and m_repeat_num. For an execution of a scheduled transaction, m_tags is set to the tags of the original scheduled transaction, while m_splits contains the execution of the original scheduled transaction splits (with TRANSID set to 0).

• Define Model_Billsdeposits::unroll(r, end_date), which returns the list (vector) of execution dates for the scheduled transaction r, until end_date. An optional argument limit can be used in order to limit the number of executions.

• Extend the main loop in mmCheckingPanel::filterTable() to also process scheduled transactions. If scheduled transactions are disabled, the loop behavior and efficiency are the same as before. The vector of transactions and the executions of scheduled transactions are processed in parallel (they are both sorted by date), choosing the entry with the smaller date in each iteration (or choosing a transaction, if both have the same date).

Interface changes

• In the header (top) area of transactions panels, show the balance information above (closer to the title) and the controls below (closer to the main action area).

• If all transactions are reconciled, then hide Reconciled Bal and Diff, since they are redundant. If at least one transaction is not reconciled, show Reconciled Bal and Diff, even if the difference is zero (this also serves as a warning to the user that there are unreconciled transactions).

Additional changes

• Rename enum cases MENU_VIEW_* to FILTER_ID_* in mmcheckingpanel.h.
• Remove VIEW_TRANS_*_STR from constants. Add FILTER_STR in mmcheckingpanel.
• Refactor Model_Checking::Full_Data constructors.
