chore(1.2): remove per-worker unit templates superseded by consolidation

The batch/cpu supervisor groups + heavy fleet replace 10 per-worker units
(reconciler/enrich/orchestrator/mutator/clusterer/campaign-clusterer/
attribution/reuse-correlator/profiler/ttp). Removed their deploy/*.service.j2
templates and rewired decnet.target to the 3 consolidated units. Dropped
test_orchestrator_unit.py (tested a removed unit). CLI commands (decnet ttp,
mutate, …) stay for manual runs; new units' Conflicts= still name the old
units defensively for hosts mid-migration.
