fix: numeric input clamping and Range Fill hotkey keystroke leak

[harshithmohan]

Summary

Fixes two interaction bugs: InputSmall now clamps numeric input to both min and max (previously only max, and not for max={0}), and pressing the r hotkey no longer leaks an r into the Range Fill modal's autofocused number input. Relates to the Range Fill flow in EditReleaseInfoModal.tsx.

Changes

Fixed

• InputSmall.tsx: honor a max bound of 0 (the old truthiness check max && ... disabled clamping for max={0})
• InputSmall.tsx: enforce min symmetrically — the prop was passed to the input but never checked in the handler
• InputSmall.tsx: deliver out-of-range values through a prototype-cloned event target instead of mutating the shared event.target, which previously wrote through to the real DOM input outside React's controlled-value flow
• EditReleaseInfoModal.tsx: r hotkey now sets preventDefault: true (react-hotkeys-hook v5 only prevents default when explicitly asked), so the keystroke is no longer typed into the autofocused "Range Starting Number" input

Verification

• pnpm lint, pnpm tscheck, pnpm test (186/186) pass
