feat(cdc): expose CDC routes over REST (on main + beta protospack)

Re-applied onto fresh origin/main. pipelinesV2: live-status/pause/unpause/
restart/reset-state routes (per-route @RequireSomePermission — GET for status,
UPDATE for mutations — matching main's current auth convention). connection-test:
POST /connection-test/cdc-prerequisites. inputs: POST /inputs/cdc -> InputCreateCdc.
Consumes protospack 3.40.0-beta.15-cdc.0 tarball; CI guard added.
