Investigate duplicate record creation on mouse bounce or accidental manual refresh

[Kris Deugau]

While auditing a live record set multiple cases of duplicate entry records were found. Several were likely due to mouse bounce causing double submission due to identical timestamps; some were more likely accidental refresh.

Investigate a session hash/flag on new records to prevent duplicates. This should NOT break the use-case of "submit, back, tweak, submit variant" as that's a far faster way of adding multiple similar records than going around the whole "Add record" loop.
