docs(skill): update formSubmitted trigger docs for multi-form support

Reflect the formId(formId) -> formIds[] change across skill + CLI + docs:
- skill api-reference/trigger-types.md: formIds array config + legacy note
- skill guides (automation-guide.md, cli-reference.md): --form-ids <csv>
- inkreach-cli: add --form-ids option (csv parse), keep --form-id legacy
- docs/automation/triggers.md: P1 formSubmitted marked done
- docs/automation/README.md: formSubmitted config fields updated
