refactor(web): fold repeated overrides into ui defaults

[juliusmarminge]

• MenuItemLabel truncates by default; every label is a single line and the
  four sites that asked for it were the ones long enough to notice.
• MenuCheckboxItem's label column is minmax(0,1fr) so labels can truncate;
  two consumers patched this per site.
• PopoverTitle is text-sm; three of four consumers shrank it from text-lg.
• Empty title and description drop text-foreground / text-sm, which the
  base already applies, and the /78 description tint and mt-2 nudge, so the
  three hero empty states match every other Empty.

Lowers the no-restyle ceiling from 1124 to 1105.

Part of the components/ui className cleanup (audit and guardrail: #12982). Each layer of stack #12993 lowers the shadcn/no-restyle ceiling; CI fails if the count rises.

Summary by CodeRabbit

• Style
  • Standardized empty-state and onboarding typography by relying on consistent default styling.
  • Added consistent spacing between empty-state descriptions and preceding content.
  • Updated popover titles to use a smaller, consistent text size.
  • Improved menu label handling and available text space across project, editor, usage, and pull request controls.
  • Refined checkbox and filter menu layouts for more reliable label alignment.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This refactor changes shared production UI defaults for menus, popovers, and empty states, affecting multiple existing product surfaces rather than only removing local duplication. Human review is warranted to confirm the intended visual and layout changes across those consumers.

No code changes detected at 0ffb1c8. Prior analysis still applies.

📝 Walkthrough

Walkthrough

The change updates shared menu, popover, and empty-state defaults, removes local styling overrides from consuming components, and lowers the restyle lint finding ceiling.

Changes

UI restyling

Layer / File(s)	Summary
Shared menu, popover, and empty-state styling apps/web/src/components/ui/menu.tsx, apps/web/src/components/ui/popover.tsx, apps/web/src/components/ui/empty.tsx	Menu labels now truncate, checkbox content columns use constrained sizing, popover titles use text-sm, and adjacent empty descriptions receive 1px top spacing.
Menu and popover consumers apps/web/src/components/ProjectScriptsControl.tsx, apps/web/src/components/chat/*, apps/web/src/components/device/*, apps/web/src/components/pullRequest/*, apps/web/src/components/usage/*	Consumers remove local truncation, typography, and grid-column overrides. Text, selection behavior, and switch layout behavior remain unchanged.
Empty-state styling and lint ceiling apps/web/src/components/NoActiveThreadState.tsx, apps/web/src/components/NoProjectsHero.tsx, apps/web/src/routes/_chat.index.tsx, scripts/lint-restyle-ceiling.ts	Empty states use default component styling while preserving their content and conditional guidance. The lint finding ceiling changes from 1125 to 1106.

Fixed in the base instead of per site: EmptyDescription now also adds mt-1 when it follows another description.

Superseded by the reworked stack (#12993 v2). After review feedback the layers were rebuilt to add fewer props and take more opinions in the base; see the new stack for the replacement.
