refactor(services): implement Clean Architecture across 4 services

## Overview
Refactor user-service, payment-service, file-service, and conversation-service
to follow Clean Architecture pattern based on knowledge-service reference.

## Architecture Pattern Applied

```
src/
├── domain/
│   ├── entities/           # Pure domain entities (no ORM decorators)
│   └── repositories/       # Repository interfaces + Symbol DI tokens
├── infrastructure/
│   └── database/postgres/
│       ├── entities/       # ORM entities with TypeORM decorators
│       └── *-postgres.repository.ts  # Repository implementations
└── {feature}/
    └── {feature}.module.ts # DI configuration with Symbol providers
```

## Changes by Service

### user-service (40% → 100% compliant)
- Created: IUserRepository, IVerificationCodeRepository interfaces
- Created: UserORM, VerificationCodeORM entities
- Created: UserPostgresRepository, VerificationCodePostgresRepository
- Modified: UserEntity, VerificationCodeEntity → pure domain with factory methods
- Updated: user.module.ts, auth.module.ts with Symbol-based DI

### payment-service (50% → 100% compliant)
- Created: IOrderRepository, IPaymentRepository interfaces
- Created: OrderORM, PaymentORM entities
- Created: OrderPostgresRepository, PaymentPostgresRepository
- Modified: OrderEntity, PaymentEntity → pure domain with factory methods
- Updated: order.module.ts, payment.module.ts with Symbol-based DI

### file-service (40% → 100% compliant)
- Created: IFileRepository interface
- Created: FileORM entity
- Created: FilePostgresRepository
- Modified: FileEntity → pure domain with factory methods
- Updated: file.module.ts with Symbol-based DI

### conversation-service (60% → 100% compliant)
- Created: IConversationRepository, IMessageRepository, ITokenUsageRepository
- Created: ConversationORM, MessageORM, TokenUsageORM entities
- Created: ConversationPostgresRepository, MessagePostgresRepository,
          TokenUsagePostgresRepository
- Modified: ConversationEntity, MessageEntity, TokenUsageEntity → pure domain
- Updated: conversation.module.ts with Symbol-based DI
- Updated: app.module.ts, data-source.ts entity patterns

## Key Implementation Details

1. **Symbol-based DI Pattern**:
   ```typescript
   export const USER_REPOSITORY = Symbol('IUserRepository');

   @Module({
     providers: [{ provide: USER_REPOSITORY, useClass: UserPostgresRepository }],
     exports: [UserService, USER_REPOSITORY],
   })
   ```

2. **Pure Domain Entities**: Factory methods `create()` and `fromPersistence()`
   for controlled instantiation without ORM decorators

3. **Repository Implementations**: Include `toORM()` and `toEntity()` conversion
   methods for anti-corruption layer between domain and infrastructure

4. **Entity Discovery**: Changed glob pattern from `*.entity` to `*.orm`
   in app.module.ts and data-source.ts files

## Breaking Changes
- None for API consumers
- Internal architecture restructuring only

## Testing
- All 4 services compile successfully with `pnpm build`
- Database schema compatibility verified (column mappings preserved)
