Deprecate runtime theme objects in favor of CSS variables (#18402)
## Summary
- **Eliminate `ICON_SIZES` / `ICON_STROKES` constants**: all icon
dimensions are now resolved at runtime via
`resolveThemeVariableAsNumber(themeCssVariables.icon.size.X)`, ensuring
values always come from computed CSS variables
- **No more consumer imports from `twenty-ui/theme`**: moved
`ColorSchemeContext`, `ColorSchemeProvider`, `ThemeColor`,
`MAIN_COLOR_NAMES`, `getNextThemeColor`, `AnimationDuration` to
`twenty-ui/theme-constants`
- **Remove `ThemeContext` / `ThemeContextProvider` / `ThemeProvider` /
`ThemeType`**: replaced across ~300 files with `themeCssVariables` (for
CSS contexts) or `resolveThemeVariable` / `resolveThemeVariableAsNumber`
(for JS runtime values)
- **Simplify provider chain**: only `ColorSchemeProvider` remains — it
toggles `light`/`dark` class on `document.documentElement` and provides
`colorScheme` via React context
- **Fix pre-existing test failures**: `useIcons.test.ts`
(non-configurable ES module spy) and
`turnRecordFilterGroupIntoGqlOperationFilter.test.ts`
(`Omit<RecordFilter, 'id'>` type mismatch)
### Theme access pattern (before → after)
| Context | Before | After |
|---------|--------|-------|
| CSS (Linaria) | `${({ theme }) => theme.font.color.primary}` |
`${themeCssVariables.font.color.primary}` |
| JS runtime (icon size, animation) | `theme.icon.size.md` /
`ICON_SIZES.md` |
`resolveThemeVariableAsNumber(themeCssVariables.icon.size.md)` |
| Color scheme check | `theme.name === 'dark'` |
`useContext(ColorSchemeContext).colorScheme === 'dark'` |

chore(twenty-front): migrate command-menu, workflow, page-layout and UI modules from Emotion to Linaria (PR 4-6/10) (#18342)
## Summary
Continues the Emotion → Linaria migration (PR 4-6 from the [migration
plan](docs/emotion-to-linaria-migration-plan.md)). Migrates **311
files** across four module groups:
| Module | Files |
|---|---|
| command-menu | 53 |
| workflow | 84 |
| page-layout | 84 |
| UI (partial - first ~80 files) | ~80 |
| twenty-ui (TEXT_INPUT_STYLE) | 1 |
| misc (hooks, keyboard-shortcut-menu, file-upload) | ~9 |
### Migration patterns applied
- `import styled from '@emotion/styled'` → `import { styled } from
'@linaria/react'`
- `import { useTheme } from '@emotion/react'` → `import { useContext }
from 'react'` + `import { ThemeContext } from 'twenty-ui/theme'`
- `${({ theme }) => theme.X.Y.Z}` → `${themeCssVariables.X.Y.Z}` (static
CSS variables)
- `theme.spacing(N)` → `themeCssVariables.spacing[N]`
- `styled(motion.div)` → `motion.create(StyledBase)` (11 components)
- `styled(Component)<TypeParams>` → wrapper div approach for non-HTML
elements
- Multi-declaration interpolations split into one CSS property per
interpolation
- Interpolation return types fixed (`&&` → ternary `? : ''`)
- `TEXT_INPUT_STYLE` converted from function to static string constant
(backward compatible)
- Emotion `<Global>` replaced with `useEffect` style injection
- Complex runtime-dependent styles use CSS custom properties via
`style={}` prop
### After this PR
- **Remaining files**: ~400 (object-record: ~160, settings: ~200, UI:
~44)
- **No breaking changes**: CSS variables resolve identically to the
previous Emotion theme values
