This give a consistent output of 3 values where using just choices leads to ValueError when choices is a list of strings. By using match from iter_choices we also keep from doing the check twice so there should be no costs here except for the zip() when using lists of strings.

Error introduced in spiral-project#1290. Fixes spiral-project#1293. WTForms needs to be bumped to >=2.3.2 as it includes a fix to `SelectField` which is required for this change to work. See: - https://wtforms.readthedocs.io/en/3.1.x/changes/#version-2-3-2 - pallets-eco/wtforms#598

This may assist with #464 (at least the behavior described by @ftm in that ticket.)
In the validation phase, we use iter_choices now instead of trying to iterate on choices directly. This will mean that regardless of list of tuples or the shortcut list of strings, we always have 3 values when we iterate the list. We use the match result from iter_choices instead of doing the comparison again to save the operation.
If you are using the shortcut list of strings and getting
'too many values to unpack (expected 2)', this is the fix.I'm doing the following to work around this right now:
list(zip(is required to preventchoicesfrom being an iterator.listTimezones()is a singleton function that returns a cached list of strings. Without thelist(zip(or this patch, this will will always fail to validate.
