When a workspace is created without an explicit content_language,
`data_get($data, 'content_language')` returns null, array_filter drops the key,
and the column falls back to its DB default of 'en'. So AI content and
notifications came out in English even when the app was running in another
locale.
Default to `app()->getLocale()` instead, so a new workspace inherits the user's
current language. An explicit content_language still wins.
Replace free-text brand_tone/brand_voice_notes with a single structured
brand_voice_traits JSON column backed by the BrandVoiceTrait enum, exposed
as choice-chip pills in the brand settings UI and autofillable from a site.
Brand voice and visuals become per-automation toggles on the Generate node.
Unify the image controls into one 0-10 picker (0 = text-only, 1 = single,
2+ = carousel) and feed the generator the most restrictive selected network
so copy fits every platform. Pass that same platform context through the
humanizer pass — extracted into a shared ResolvesPlatformCopyBudget trait —
so the rewrite can no longer drift past the character cap the generator
respected, in both the automation and manual creation flows.
Persist the trigger node's schedule editor fields on save (they were
silently dropped by validated() for lacking validation rules).
