Bank Rec / Cash Rec/Till tweaks and fixes

• The bank rec screen would sometime show unexpected / random alt codes in the Src field. e.g. you expect to see Rebate Income, but it shows GST owing. Visual display bug only. Now fixed.
• Removed some non functional / residual code linked to old bank rec mechanisms. Not impactful except maybe made new recs a tiny bit slower to save. More cleaning out unneeded junk

A new bank rec needs to cross check with prior bank rec to figure out what is held over, ignored etc to deal with in this new rec. The algorithm to figure out which rec to use is complicated by fact that recs can cover overlapping periods etc. Older versions of c9 simply grabbed the most recent rec that happened to start before period we are recing. But this was highly problematic because if you redid an ancient rec, this rec would become the latest, even if it was months/years prior to next period to rec.  A proper algorithm needs to consider the most recent rec only if it recs upto the last txn prior to new rec period, otherwise it needs to get the rec that comes closest to beginning of new rec period.

But an issue here: it is possible to do a bank rec where you set to date into the future. So this becomes a rec which is opinionated about closing balance it cannot possibly know.  Under some circumstances things could line up and these recs would get selected dropping in a massive tonne of discordant txns since every legit txn that happened after it was created would be from point of view of this rec, be a rec breaking txn. So tweaked algorithm a bit to generally ignore / distrust recs that claim to know more than a day into future except under some special/specific circumstances (e.g. when we are recing from a period we know happens to be on or before the recs creation date).
