/**
|
|
* @file companyAutomat.js
|
|
* @description Manages configuration details of the currently selected company
|
|
* (tax rates, currency, language, legal details, and root category ID).
|
|
*
|
|
* Upstream Triggers:
|
|
* - `authAutomat`: Subscribes to auth state changes — triggers `actions.load()`
|
|
* when status is `'authed'` with a `selectedCompanyId`, and `actions.reset()` on `'anon'`.
|
|
* - UI / Settings: Calls `update(payload)` or manual `load()`.
|
|
*
|
|
* Downstream Triggers:
|
|
* - `categoryAutomat`: Subscribes to `companyAutomat` — triggers `actions.loadTree()`
|
|
* whenever `company.current.id` or `rootCategoryId` changes/becomes available;
|
|
* resets when company is unset.
|
|
* - `posterminalAutomat`: Reads `companyAutomat.state.current?.id` as a fallback company ID.
