feat(cms): enable draft/publish + version history on Globals/Collections (MITHOME-92)

Adds versions.drafts to all content-bearing Globals (Home, About,
Services, Contact, Common) and Collections (LegalPages, Partners) via
shared config in src/lib/payload-versions.ts. Media and Users are
deliberately excluded (no draft workflow needed for uploads/auth).

This is the direct successor to the old custom CMS's "Verziók panel"
(MITHOME-64): the Payload admin now shows Save Draft / Publish changes
and a Versions tab with history/diff/restore per document.

Fixes a real bug found during manual verification: Payload's `_status`
field defaults to 'draft' when a create/update call's data omits it,
and that value is preserved on subsequent updates rather than being
overwritten. Since migrate-content-to-payload.ts never passed
`_status`, every migrated document ended up in draft status, which
would have broken public pages once combined with any future explicit
draft read. Fixed by explicitly setting `_status: 'published'` on
every write in the migration script.

Verified live in the browser:
- Payload admin: Home global shows Status: Published, Save Draft /
  Publish changes buttons, Versions tab with history (draft -> current).
- Saving a draft edit (title change, not published) does NOT change
  what /hu and /en render — confirmed by reloading the public page
  before publishing.
- Publishing the change updates the public page as expected.
- Full gate green: tsc, lint, tests (58 passed), production build.
