feat: introduce index layout skill for FULL_PAGE index/list tables

- Added a new skill for managing index and list table layouts in the ERP project, detailing layout and data contracts.
- Updated project guidelines to reference the new index layout skill.
- Introduced rules for page composition, column definitions, audit fields, action column width, and toolbar functionality.
- Created utility functions for computing action column width and formatting audit fields, along with corresponding unit tests to ensure reliability.

These changes enhance the application by providing a structured approach to index layouts, improving consistency and usability across the ERP project.

name: index-layout
description: Use whenever building or editing a FULL_PAGE index / list table in the ERP project (master-data lists, transaction lists, system users/privileges, any EnterpriseDataTable index). Governs LAYOUT and table contracts ONLY — page chrome, module columnDefs vs shared prefix/postfix columns, action-column width, audit field names, and the search/filter/reload toolbar. Does not govern colors, fonts, border-radius, or other visual styling. Trigger this any time an index page, list table, row-action column, audit columns, or index toolbar is added or restructured — including when the user says "build a list page", "index table", or "add a refresh button".

# Index Layout
Layout and data contracts for **FULL_PAGE index / list tables**. Visual style (color, weight, radius, shadows) belongs to `@repo/ui`, not this skill.
Walk these rules in order whenever you add or change an index table.
## Project chrome (do not rebuild)
Index routes already render inside `EnterpriseIndexPageProvider``EnterpriseDataTable`. That chrome owns:
- Page header (title, description, breadcrumbs, Create)
- Toolbar: search, filter, **reload**
- Prefix columns: selection, row actions, status
- Postfix columns: Created by, Created at, Updated by, Updated at
- Pagination / server-side row model
**Do not** re-implement the toolbar, action column, status column, or audit columns in a module page. This skill governs the **`columnDefs` you pass in** and the **entity/transformer field names** the shared table reads.
## 1. Page composition
```tsx
<EnterpriseIndexPageProvider pageHeaderProps={{ title, description, icon, breadcrumbs }}>
<EnterpriseDataTable columnDefs={columnDefs} filterConfig={filterConfig} />
</EnterpriseIndexPageProvider>
```
Copy `example/full-page`. Do not invent a third index layout.
## 2. Module `columnDefs` = business fields only
Module index pages declare **business columns only** (code, name, relations, flags).
Do **not** redeclare:
- `action_column` / row actions
- `status` (the shared status badge column)
- `createdBy` / `createdAt` / `updatedBy` / `updatedAt`
```tsx
// GOOD
const columnDefs = [
{ field: 'username', headerName: t('common:fields.username'), minWidth: 160 },
{ field: 'privilege', headerName: t('common:fields.privilege'), valueGetter: ({ data }) => relationLabel(data?.privilege) },
];
// BAD — duplicates shared chrome
const columnDefs = [
{ colId: 'action_column', width: 180 },
{ field: 'created_at', headerName: 'Created at' },
];
```
## 3. Audit fields are camelCase
API and transformers map:
| Entity field | Meaning |
|---|---|
| `createdBy` | actor string, `{ username }`, or uuid |
| `createdAt` | unix ms |
| `updatedBy` | actor string, `{ username }`, or uuid |
| `updatedAt` | unix ms |
`EnterpriseDataTable` postfix columns bind those names and fall back to legacy snake_case (`creator_name`, `created_at`, `editor_name`, `updated_at`) for leftover local/Pouch rows.
Empty values render as `-`. Nested actors display `username` || `name` || `id`.
Do not alias audit fields to snake_case in TrackGo transformers.
## 4. Action column width is shared
Row actions stay a single nowrap icon row (`RowActions` with `responsiveView={false}`). Width is computed in `EnterpriseDataTable` from privileges + `moduleType` (`View` always, then Edit / Duplicate / Activate-or-Deactivate or transaction flags / Delete). `flex: 0` so the column does not shrink.
Do **not** override action column `width` / `minWidth` in module `columnDefs` or `customPrefixColumn` unless the module adds extra custom row actions **and** you widen via `customPrefixColumn` to fit them.
## 5. Toolbar always includes reload
The index toolbar is search + filter + reload. Reload must call `gridApi.refreshServerSide({ purge: true })` (same as search/filter) — **not** `window.location.reload()`.
Label: `common:actions.reload` (“Reload” / “Muat Ulang”). Icon: `RefreshCw`.
Do not add a second module-level refresh control that duplicates this.
## Checklist
- [ ] Index page uses `EnterpriseIndexPageProvider` + `EnterpriseDataTable` (no custom table chrome)
- [ ] `columnDefs` are business fields only
- [ ] Transformer maps `createdAt` / `createdBy` / `updatedAt` / `updatedBy`
- [ ] Action column width left to the shared table
- [ ] Reload is the shared toolbar button, not a full browser refresh
