refactor: migrate to clean architecture with trait-based DI (v0.2.0)

Complete architectural overhaul across all 12 crates:

- Replace validator crate with zod-rs for all DTO validation
- Replace manual pagination with paginator-rs/paginator-sea-orm
- Migrate all modules (iam, cms, gacha, dimentorin) to clean architecture:
  domain → application → infrastructure layers
- Introduce trait-based DI (Arc<dyn Trait>) at every layer for repositories and services
- Delete all v1/ legacy SurrealDB-era code across every crate
- Replace opaque response helpers with typed IntoResponse structs (ApiSuccess, ApiCreated, ApiPaginated, ApiMessage)
- Remove dual_mode_repository, migration_validation_errors, validator.rs dead code
- Zero cargo clippy warnings; release build clean
