"""Coerce a missing color_scheme to the default on create/write.

`web_enterprise` declares `color_scheme` as required with default 'system',
and the DB column is NOT NULL. It also adds a radio widget for
`res.users.color_scheme` (a related field) to the user form. For a brand-new
user the underlying `res.users.settings` record doesn't exist yet, so the
widget loads with no value and submitting the form propagates
`color_scheme=False` into the eventual settings create/write — which trips the
NOT NULL constraint and surfaces as "Missing required value for the field
'Color Scheme'".

Treat a falsy color_scheme as 'omit' so the field's own default applies.
