Remove twenty-ui-deprecated and migrate frontend to twenty-ui (#21596)

Migrates `twenty-front`, `twenty-sdk`, and
`twenty-front-component-renderer` from `twenty-ui-deprecated` to
`twenty-ui` (mechanical import swap — the packages have API parity) and
deletes the deprecated package along with its workspace/CI/config
wiring.

Also adds `@linaria/react`/`@linaria/core` as direct deps of
`twenty-front` (it used them transitively via the deprecated package).

Note: move the required status check from `ci-ui-status-check` to
`ci-new-ui-status-check`.

Argos: the Storybook box-model/button-reset baseline shift (the bulk of
the visual diffs) is isolated in #21665 — Storybook now loads
twenty-ui's global `reset.scss`, which the production app already ships.
Once #21665 merges and this branch is rebased, the remaining Argos diffs
are component-level visual-parity items only.
