Fix design system violations and logic bugs from code review

- Remove backdrop-filter blur (glass effect) from TopBar; use opaque ink-1 background
- Remove decorative glow box-shadows from market status dot
- Fix button border-radius: var(--r-2) → var(--r-1) (4px → 2px) per design rules
- Replace invented hover color rgba(194,170,122,0.04) with var(--ink-3) token
- Add missing .psm-signal.neu CSS rule so neutral signals have visual treatment
- Use HTML disabled attribute on nav buttons instead of aria-disabled alone
- Replace duplicate EPS KPI tile with Prev Close to remove redundancy with P/E sublabel
- Rename sortIndices → limitIndices (function only truncates, never sorts)
