feat(05-02): IPC handlers, preload bridge, and ServiceGraph wiring for budget enforcement

- Create ipc-budget-handlers.ts with 6 budget channel handlers (save/delete/list policies, list/resolve incidents, get status)
- Add budgetService to RegisterDomainHandlersDependencies interface
- Register budget handlers in ipc-domain-handlers.ts composition
- Add BudgetEnforcementService lazy slot in service-graph.ts with getOrCreateBudgetEnforcementService
- Pass budgetService to domain handler registration in main-runtime-support.ts
- Fix preload bridge to pass {companyId} object for listBudgetPolicies and getBudgetStatus
- D-06: checkAutoResolve called on saveBudgetPolicy to auto-resolve incidents on limit increase
