feat(dealix): py3.10/3.11 compat shim + 54 unit tests for business/innovation/ai

PROBLEM
The codebase used Python 3.11+ stdlib features (`from datetime import UTC`,
`from enum import StrEnum`) in 22 files, breaking local dev on Python 3.10
(Windows users) and any pytest run that imports the affected modules.

SOLUTION
1. New `core/_py_compat.py` providing UTC + StrEnum shims that:
   - On 3.11+ re-export the stdlib names (zero overhead)
   - On 3.10 fall back to `timezone.utc` and a (str, Enum) backport

2. All 22 affected files patched to import from the shim:
   - core/utils.py, core/config/models.py
   - api/routers/admin.py
   - auto_client_acquisition/{ai/model_router, agents/{intake,icp_matcher},
     v3/{memory,agents,compliance_os,market_radar},
     personal_operator/{operator,memory,launch_report},
     innovation/{proof_ledger_repo,command_feed_live}}.py
   - autonomous_growth/agents/sector_intel.py
   - dealix/{trust/{approval,tool_verification,policy},
     observability/cost_tracker,
     contracts/{evidence_pack,event_envelope,audit_log,decision},
     classifications/__init__,
     governance/approvals}.py

3. Three new test suites for previously-untested layers (54 tests):
   - tests/unit/test_business_suite.py — gtm_plan, launch_metrics,
     market_positioning, pricing_strategy, proof_pack, unit_economics,
     verticals (28 tests covering plan recommendation, performance fee,
     ROI math, account health grading, vertical playbook structure)
   - tests/unit/test_innovation_suite.py — aeo_radar, command_feed,
     deal_rooms, experiments, growth_missions, proof_ledger, ten_in_ten
     (18 tests covering deterministic reproducibility, card type taxonomy,
     pending-approval invariant, kill-mission visibility)
   - tests/unit/test_ai_model_router.py — ModelTask + get_model_route +
     estimate_model_cost_class + requires_guardrail (8 tests covering
     enum integrity, route round-trip, guardrail bool contract)

VERIFICATION
- ast.parse green on all 22 patched files
- pytest tests/unit/ → 477 passed, 2 skipped (provider smoke needs API keys)
  on Python 3.10.12 venv with project requirements installed
- No behavior change on 3.11+: the shim re-exports stdlib symbols
