Subject: [PATCH] refactor(app): provide sub-config structures from main config

Extract DatabaseConfig, RedisConfig, RustFSConfig, LogConfig, and EmailConfig
from the main Config to enable pkg/* package constructors to receive specific
config types by value, supporting the fx.Lifecycle OnStop hooks pattern.
