Fast-follows for the new layout / flat redesign (master:
twentyhq/core-team-issues#2478).
## Changes
- **Main navbar 48px** (twentyhq/core-team-issues#2479) —
`SIDE_PANEL_TOP_BAR_HEIGHT` 40 → 48, so `PageCardHeader` matches the
Figma target. The side panel top bar shares this constant and stays
aligned.
- **Content panel 12px radius** (twentyhq/core-team-issues#2480) —
`PageCardLayout` card gets a full border + 12px radius and an 8px inset
(`spacing[2]`) so it floats on the shell instead of square full-bleed.
- **Square three-dots button** (twentyhq/core-team-issues#2481) — added
a `square` option to `AnimatedButton`; the page-header side-panel toggle
now renders a 24×24 square icon button instead of a 32×24 pill.
- **Table checkbox sizing** (twentyhq/core-team-issues#2482) — restored
`box-sizing: content-box` on the checkbox box. Its border is declared
outside the label size, so the global `border-box` reset (#21349) was
shrinking it (14px → 12px). Same fix pattern as #21349.
- **Tertiary navbar background** (twentyhq/core-team-issues#2483) — left
navbar / app shell use `background/tertiary` instead of the noisy
surface (`DefaultLayout`, `UserOrMetadataLoader`).
- **Skeleton loading** (twentyhq/core-team-issues#2484) — metadata +
content loading now match the new layout: tertiary shell, 12px rounded
content panel, 48px navbar, sparse bars, empty body (removed the dense
full-width rows). Left-panel skeleton bars use `quaternary` so they stay
visible on the tertiary shell.
## Verification
- typecheck (tsgo) + oxlint + oxfmt pass for all changed files.
- Verified live against a running workspace: measured navbar = 48px,
three-dots = 24×24, checkbox box-sizing = content-box (14px), card
radius = 12px, shell background = tertiary (no noisy image).
Content-loading skeleton matches the target.
## 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`.
