feat: ga-core + ga-api + ga-batch + V13-V15 + Docker + frontend skeleton

ga-core (22 tables):
- user/role: VO + Mapper + XML (login + RBAC)
- org: Grade, Organization (CTE recursive tree), Agent + history
- product: InsuranceCompany, Product, Contract
- rule: CommissionRate, PayoutRule, OverrideRule, ChargebackRule, ExceptionTypeCode
- receive: CompanyProfile, FieldMapping, CodeMapping, RawCommissionData, ParseError
- ledger: Recruit, Maintain, Exception (batch insert + cursor)
- settle: SettleMaster (UPSERT), Override, Chargeback, Payment, Reconciliation, BatchJobLog
- All XMLs use EncryptTypeHandler for PII fields

ga-api:
- AuthController: login (lock on N fails), refresh, me, password, logout
- Domain controllers: Agent, Organization, Contract, Company, Product, Rule,
  Receive, Ledger (recruit/maintain/exception + approve), Settle (confirm/hold/release),
  Payment, User, Role (matrix), BatchTrigger
- All use @RequirePermission + @DataChangeLog

ga-batch:
- MonthlySettlementJob: 8 Steps (receiveData, transformData, reconcile,
  calcRecruit, calcMaintain, chargebackException, calcOverride, aggregate)
- DataReceiver strategy + ManualReceiver, MappingEngine stub
- CommissionCalculator (pct/tax via MoneyUtil), JobLauncherController

DB V13~V15:
- V13: 14 indexes (settle_master, ledgers, contract, chargeback, payment, raw, logs)
- V14: create_monthly_partition() helper function
- V15: v_agent_monthly_summary, v_org_settle_summary, v_chargeback_risk views

Infra:
- docker-compose: postgres + redis + api + batch + frontend
- Multi-stage Dockerfile (gradle build → JRE)

ga-frontend (skeleton):
- Vite + React 18 + TypeScript + AntD 5 + AG Grid + React Query + Zustand
- API request layer (axios + JWT), LoginPage, MainLayout (dynamic menu), Dashboard
- nginx.conf for /api proxying
