Rename twenty-ui to twenty-ui-deprecated and twenty-new-ui to twenty-ui to prepare package release (#21315)

## Description

Promotes the next-gen UI library (formerly `twenty-new-ui`) to the name
**`twenty-ui`** (v0.1.0, publishable) and renames the old package to
**`twenty-ui-deprecated`**. Rewrites ~1,730 `twenty-ui` imports →
`twenty-ui-deprecated`, updates all configs/CI/Docker/deps, and migrates
twenty-front's `Toggle` to the new package (first consumer) as a
drop-in.

## Next steps
- Wire the `ui/v*` publish dispatch (`cd-deploy-tag.yaml` +
`.yarnrc.yml`), then tag `ui/v0.1.0` to publish.
- Continue migrating components from `twenty-ui-deprecated` →
`twenty-ui`.
