Charles Bochet eda905f271 [DevXP] Improve Linaria pre-build speed (#18382)
## Summary

This PR improves Linaria/WYW pre-build speed and continues the migration
of `twenty-ui` components away from runtime `ThemeContext` reads toward
static CSS variables and theme constants.

### Linaria/WYW profiling plugin improvements (`twenty-shared`)

- **Babel JIT warmup**: added a `buildStart` warmup step that triggers
WYW's Babel JIT compilation before the real build starts, so the first
real file doesn't pay the cold-start penalty
- **`configResolved` hook**: detects dev vs prod mode and resolves the
correct warmup file path relative to `config.root`
- **Dev-only per-file logging**: slow file warnings are now gated behind
`isDevMode`, keeping production/CI build output clean
- **`closeBundle` summary**: moved the final top-slow-files report to
`closeBundle` for accurate end-of-build reporting
- **Removed noisy progress interval logging** in favor of the warmup log
+ final summary

### Migration from `ThemeContext` to static CSS variables / constants

Across `twenty-ui`, replaced runtime `useTheme()` reads with:
- `themeCssVariables` CSS custom properties (colors, spacing)
- Hard-coded design-system constants (`ICON.size.md` → `16`,
`ICON.stroke.sm` → `1.6`) so components no longer need a React context
at render time — enabling Linaria static extraction

**Components migrated:**
- `Button`, `AnimatedButton`, `LightButton`, `LightIconButton`,
`AnimatedLightIconButton`, `ButtonIcon`, `ButtonSoon`
- `ProgressBar` (Framer Motion width animation → CSS `transition`)
- `Info`, `HorizontalSeparator`, `LinkChip`
- `MenuPicker`, `MenuItemLeftContent`, `MenuItemIconWithGripSwap`,
`NavigationBarItem`
- `JsonArrow`, `JsonNestedNode`
- `ModalHeader`

### Other
- Added `aria-valuenow` to `ProgressBar` for accessibility
- `VisibilityHidden` component updated to inline accessibility styles
