Migrate twenty ui to jotai (#17900)

## Remove Recoil from twenty-ui

Completely removes the `recoil` dependency from `twenty-ui` by
converting all atoms, hooks, and providers to Jotai equivalents.

### twenty-ui
- `createState` now returns a Jotai `PrimitiveAtom` instead of a Recoil
atom
- `iconsState`, `IconsProvider`, `useIcons` converted to Jotai
(`useSetAtom`, `useAtomValue`)
- `RecoilRootDecorator` now uses Jotai `Provider` (name kept for compat)
- Deleted unused `invalidAvatarUrlsState` (Avatar already uses
`invalidAvatarUrlsAtomV2`)
- Removed `recoil` from `package.json`

### twenty-front
- Created local Recoil `createState` at
`@/ui/utilities/state/utils/createState` for ~112 state files still on
Recoil
- Updated all imports accordingly
- Removed `iconsState` from Recoil snapshot preservation in `useAuth`
(lives in Jotai store now)
