Initial implementation of the eec-campaigns tool

Drives listmonk's real Campaign API from git-authored Markdown+frontmatter,
so broadcast/segment emails get listmonk's mature unsubscribe/bulk-send/
attachment handling instead of reimplementing it. sync only ever creates or
updates a draft (idempotent, diff-based, refuses to touch a non-draft
campaign); a pushed send/<slug> tag or manual workflow run is the only way
to actually trigger a send. Includes list-name resolution, segment_query
materialization into managed lists, content-hash-deduped attachment
uploads, and an automatic post-sync preview email.

// Package listmonk is a small client for the listmonk REST calls
// eec-campaigns needs: managing campaigns (create/update/status/test),
// resolving list names to IDs, uploading media for attachments, and
// materializing a segment_query into list membership. Deliberately not
// shared with eec's or drip's own listmonk clients — same reasoning drip's
// client comment already gives: Go's internal/ visibility rules would block
// it anyway, and this client's needs (campaigns, media) diverge enough from
// eec's (transactional sends) and drip's (subscriber sweep) that duplicating
// the small HTTP-plumbing overlap beats a shared module.
