Fixes a spurious "changed" flag on any campaign without an explicit
template_id, which was re-syncing and re-previewing campaigns like
welcome/campaign.md on every unrelated push.
Matches the pattern already in place for the other domain repos: a
short domain-specific README instead of the generic campaigns-template
one (also fixing a stray "from" -> "from_email" field-name error), and
a sample welcome campaign using the correct "cateconners-list" name
from the start.
