Reorganize twenty-ui into best-practice component domains and per-component folders (#21745)

Reorganizes `twenty-ui`'s component organization to follow how the best
UI libraries (MUI, Mantine, Base UI, Polaris) structure their source,
now that the package has stabilized.

**Taxonomy** — dissolves the meaningless `components/` junk-drawer and
the 107-file `display/` mega-category. New domains/subpaths:
`data-display`, `typography`, `icon`, `surfaces`; `feedback` and
`layout` absorb the rest (banners/callout/info + placeholders →
feedback; modal/card → surfaces; motion + separators → layout).

**Per-component layout** — every component is now
`<domain>/<ComponentName>/<ComponentName>.tsx` with colocated
styles/stories/types, `internal/` for private helpers and `parts/` for
re-exported compound sub-parts. The redundant inner `/components/` is
gone. `icon` and `json-visualizer` are kept as cohesive subsystems.

**Also:** adds a tree-shakeable root barrel (`import { Button } from
'twenty-ui'`), the generator now owns `individual-entry.ts`, and a real
barrel-leak bug is fixed (private `internals/` parts were leaking into
the public API).

Consumer imports (~1.2k files) and the `twenty-sdk` UI aggregator were
updated by codemod. The change is **export-neutral** except 16
intentionally-removed private internals symbols (all verified
unconsumed). Gates green: typecheck, lint, build, size-limit, storybook.
