Setting model

Mongoose model: Setting
Source: src/models/setting.model.ts
Interface: ISetting

Fields

Field	Type	Required	Default	Description
`isDummyOrder`	boolean	No	`false`	Route all orders to `DummyOrder` instead of live Kite
`created_at`	Date	Auto	—	Created timestamp
`updated_at`	Date	Auto	—	Updated timestamp

Only one document is expected in the collection.
SettingController.getSetting returns the first document found.
updateSetting upserts if no document exists.
Controllers check isDummyOrder at runtime to choose Order vs DummyOrder model and skip Kite API calls.
