feat(P41): per-environment CI jobs + environment workflow input

---ci---
project: acdl
phase: 41
milestone: v1.9

---/ci---

Phase 41 — per-environment-ci-jobs (REQ-105, REQ-106, D-082):

Per-env contracts (REQ-105):
- contracts/static-assets.{dev,qa,prod,dr}.yaml + microservice.{dev,qa,prod,dr}.yaml
  (8 files, each sets environment: to its own name, uses interpolation).
- Default contracts/static-assets.yaml + microservice.yaml preserved (backwards compat).

Deploy workflow environment input (REQ-106):
- .github/workflows/deploy.yml + .gitea/workflows/deploy.yml (byte-identical):
  new 'environment' workflow_call input (default empty, override).
- scripts/run_platform.sh: --environment <name> flag; exports
  ACDL_ENVIRONMENT_OVERRIDE; re-runs env check against the override.
- core/contract_resolver.py: resolve(environment_override=...) (D-088);
  CLI honors --environment flag + ACDL_ENVIRONMENT_OVERRIDE env var.

Consumer guide (REQ-106):
- docs/consumer-guide.md: 'Per-environment deployment' section with 4
  caller-workflow examples (dev/qa/prod/dr), HITL gate structure
  (approve_qa/approve_prod/approve_dr, D-042), interpolation reference table.
- Documents promotion-without-editing + hybrid model (per-env contracts
  OR single contract + env input).

Tests: +40 (test_per_env_contracts.py, test_deploy_workflow_env_input.py,
test_consumer_guide_per_env_section.py). 446 passed; run_ci.sh green;
deploy workflows byte-identical.
