Félix Malfait 23f5ba9ebf feat: add resizable kanban column width (#21828)
## What & why

Lets users resize the columns of a Kanban (record board) view. Requested
by a user; the design avoids the "ragged board" problem by making the
width a **single shared value**.

## Behaviour

- A drag handle appears on the right edge of every column header.
- Because all columns read **one** width value, dragging any handle
resizes **every** column together — they can never end up mismatched.
- Width is clamped between **150px** and **400px** (default **200px**).
- The width is **persisted per view** and restored on reload.

## Approach

**Backend** — a new nullable `View.kanbanColumnWidth` field, threaded
through the existing view-level setting pattern (the same one
`kanbanAggregateOperation` / `shouldHideEmptyGroups` use), so it gets
create/update/manifest/override support for free:
- entity column + `ViewOverrides` + `@WasIntroducedInUpgrade`
- `CreateViewInput` / `UpdateViewInput` (`Int`, `@Min(150)`/`@Max(400)`)
+ `ViewDTO`
- flat-view editable properties, entity-properties config, compare-type,
standard-view + manifest converters
- a fast instance command adding the `core.view` column

**Frontend** — the value hydrates into a view-scoped atom and drives a
single CSS variable set on the board container, which both column
headers and bodies read. Live dragging only writes that CSS variable (no
per-move React re-render); the final width is committed to the atom and
persisted via `updateView` on pointer-up.

## Nullability / defaults

`kanbanColumnWidth` is nullable — `null` means "never resized" and the
UI falls back to the 200px default, so existing rows need no backfill.

## Validation

- `nx typecheck twenty-server`  and `nx typecheck twenty-front` 
- `nx lint:diff-with-main twenty-server` ; frontend lint fixes applied
(split constants to one-per-file, removed `useRef`-for-state in favour
of `useState`).
- Draft pending a final green CI run (the dev container reclaimed
`node_modules` mid-session; re-running locally).

## Test plan

- [ ] Drag a kanban column edge → all columns resize together, clamped
150–400px
- [ ] Reload → width persists for that view; other views unaffected
- [ ] A view that was never resized still renders at 200px

Installation

Cloud

The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.

Build an app

Scaffold a new app with the Twenty CLI:

npx create-twenty-app my-app

Define objects, fields, and views as code:

import { defineObject, FieldType } from 'twenty-sdk/define';

export default defineObject({
  nameSingular: 'deal',
  namePlural: 'deals',
  labelSingular: 'Deal',
  labelPlural: 'Deals',
  fields: [
    { name: 'name', label: 'Name', type: FieldType.TEXT },
    { name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
    { name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
  ],
});

Then ship it to your workspace:

npx twenty app:publish --private

See the app development guide for objects, views, agents, and logic functions.
