[management] fix extend call and move config to types (#3575)

This PR fixes configuration inconsistencies and updates the store engine type usage throughout the management code. Key changes include:
- Replacing outdated server.Config references with types.Config and updating related flag variables (e.g. types.MgmtConfigPath).
- Converting engine constants (SqliteStoreEngine, PostgresStoreEngine, MysqlStoreEngine) to use types.Engine for consistent type–safety.
- Adjusting various test and migration code paths to correctly reference the new configuration and engine types.
