Jotai 13 (#18178)

## Recoil to Jotai Migration — PR 13: Workflow, Page Layout, AI,
Activities, Settings, SSE & Remaining Modules

### Summary

This is the 13th PR in the [14-PR migration
series](packages/twenty-front/src/modules/ui/utilities/state/jotai/MIGRATION_PLAN.md)
to replace Recoil with Jotai as the state management library in
`twenty-front`. This PR migrates the remaining consumer code across all
modules — updating ~1,076 files with ~10k insertions/deletions.

### What changed

**New Jotai infrastructure (13 new files):**
- `createComponentSelectorV2` and `createComponentFamilySelectorV2` —
instance-scoped derived atoms, replacing Recoil's component selectors
- 6 new hooks: `useRecoilComponentSelectorValueV2`,
`useRecoilComponentFamilySelectorValueV2`,
`useRecoilComponentSelectorCallbackStateV2`,
`useRecoilComponentFamilySelectorCallbackStateV2`,
`useRecoilComponentStateCallbackStateV2`,
`useRecoilComponentFamilyStateCallbackStateV2`
- New types: `ComponentSelectorV2`, `ComponentFamilySelectorV2`,
`SelectorCallbacksV2`
- Extended `buildGetHelper` to support the new selector patterns

**State definition migrations:**
- `createState()` → `createStateV2()` (Jotai `atom()`)
- `createFamilyState()` → `createFamilyStateV2()` (Jotai `atom()` with
family cache)
- Recoil `selector`/`selectorFamily` → Jotai derived `atom()` via V2
utilities

**Hook migrations (~2,400 removed, ~1,545 added V2 equivalents):**
- `useRecoilValue` → `useRecoilValueV2`
- `useRecoilState` → `useRecoilStateV2`
- `useSetRecoilState` → `useSetRecoilStateV2`
- `useRecoilCallback` → `useCallback` + `jotaiStore.get/set`
- `useRecoilComponentValue` → `useRecoilComponentValueV2`
- `useSetRecoilComponentState` → `useSetRecoilComponentStateV2`
- `useRecoilComponentFamilyValue` → `useRecoilComponentFamilyValueV2` /
`useFamilySelectorValueV2`
- ~397 direct `import from 'recoil'` removed

**Deleted files (9 files):**
- `dateLocaleState.ts` — consolidated
- `currentAIChatThreadTitleStateV2.ts` — renamed to replace the original
- `isCommandMenuOpenedState.ts` — removed
- `filesFieldUploadState.ts` — replaced by V2
- `recordStoreFamilySelector.ts`, `recordStoreFieldValueSelector.ts`,
`recordStoreRecordsSelector.ts` — replaced by V2 equivalents
- `settingsAllRolesSelector.ts` — replaced by `useSettingsAllRoles` hook
- `settingsRoleIdsStateV2.ts` — consolidated

**Modules migrated:**
- Workflow (diagram, steps, variables, filters)
- Page Layout (widgets, fields, graph, tabs)
- AI (chat, agents, browsing context)
- Activities (rich text editor, targets, timeline)
- Action Menu (single/multiple record actions)
- Command Menu (navigation, history, pages, workflow)
- Context Store
- Record Board, Record Table, Record Calendar, Record Index
- Record Field, Record Filter, Record Sort, Record Group
- Record Drag, Record Picker, Record Store
- Views (view bar, view picker, filters, sorts)
- Settings (roles, permissions, SSO, security, data model, developers,
domains)
- SSE (event streams, subscriptions)
- Spreadsheet Import
- Auth, Favorites, Front Components, Information Banner
