fix: Phase 2-3 DB isolation + Gate 3 data layer real connection (AGENTS.md v16.0)

**DB Isolation (P0):**
- Test connection string: kartselldb → kartselldb_test (prevents accidental production truncates)
- Production Host appsettings unchanged (kartselldb is correct for operations)

**Gate 3 Data Layer (P1):**
- Remove StubKrxDataService from ModelOperationsModule DI
- Register real KrxDataService as typed HttpClient in Program.cs
- KrxDataService already has built-in fallback to stub data when KRX_API_KEY is missing
- No behavior change for local dev (key missing → stub data); production ready (key present → real API)

**Tech Debt Registration (AGENTS.md no undocumented magic):**
- DEBT-009: PBO/Sharpe calculation simplified (needs proper CSCV methodology)
- DEBT-010: Model prediction uses fixed quantities (needs real position-sizing)
- DEBT-011: Cost 2x simulation uses linear formula (needs full re-simulation)
- DEBT-012: False-exit analysis unimplemented (always returns 0)
- DEBT-013: Plaintext DB password in appsettings.json (security debt)
- DEBT-014: Duplicate/reconciliation detection placeholders (infrastructure debt)

Gate 3 marked "rehearsal ready" (real KRX data, simplified analytics).
See TECH_DEBT_REGISTER.md for full impact/effort estimates.

| DEBT-009 | PBO/Sharpe calculation | High (3) | High (3) | Backlog | MetricsCalculator.cs:148,170 use simplified percentile formulas. Need proper CSCV-based PBO and DSR methodology. Required for production Sharpe baseline. Gate 3 rehearsal will use simplified version; full implementation deferred to separate work. | @claude | Gate 3 Rehearsal Scope |
| DEBT-010 | Model prediction logic | High (3) | High (3) | Backlog | ReplayEngine.cs:90,163 predict fixed quantities (100 units). Need actual position-sizing algorithm. Required for realistic cost simulation. Gate 3 uses fixed quantities; full implementation deferred. | @claude | Gate 3 Rehearsal Scope |
| DEBT-011 | Cost 2x simulation | High (3) | High (3) | Backlog | ShadowRunJob.cs:132 uses linear approximation (TotalReturn * 0.5m). Need full re-simulation with actual fee/slippage impact. Required for realistic scenario analysis. Gate 3 uses linear model; full implementation deferred. | @claude | Gate 3 Rehearsal Scope |
| DEBT-012 | False-exit analysis | High (3) | High (3) | Backlog | ShadowRunJob.cs:136-139, FalseExitAnalyzer.cs always returns 0. Unimplemented feature. Required for accurate sell-reason attribution. Gate 3 rehearsal does not include false-exit analysis; deferred to separate work. | @claude | Gate 3 Rehearsal Scope |
| DEBT-013 | Credentials in appsettings | High (3) | Low (1) | Backlog | Host/tests appsettings.json contains plaintext DB password (kartsell4321@!). Must migrate to Gitea Actions Secrets and environment variables. Security compliance required. | @claude | Security / Ops |
