fix: restore input bar padding and chat button alignment

[jeffgreendesign]

Summary

• Fix input bar losing bottom padding on desktop — Tailwind v4 compiles py-4 as padding-block, which overrides pb-safe's padding-bottom in the cascade. Switched to pt-4 + pb-safe and moved safe-area utilities into @layer utilities.
• Add sm:min-h-9 sm:min-w-9 to the chat Send button to match the workspace intent-bar fix from Add bottom padding offset to safe area inset utility #55.
• Affects chat, workspace, and quick-actions input bars.

Test plan

• Desktop: input, mic button, and Send button are same height on chat and workspace views
• Desktop: input bar has visible bottom padding (16px) on both views
• Mobile: buttons stay at 44px touch target
• npm run gates passes

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.

Walkthrough

This pull request addresses a CSS specificity issue where Tailwind v4's padding-block cascade was overriding iOS safe area inset padding (pb-safe). The fix involves three main changes: (1) moving safe area inset utility classes into Tailwind's @layer utilities block in globals.css to improve cascade resolution, (2) updating the padding approach in input bar containers across multiple components from uniform vertical padding (py-4) to top-only padding (pt-4), and (3) adding responsive sizing to a chat submit button. These changes restore proper padding handling on desktop while maintaining safe area considerations on mobile.

1252-1270: ⚠️ Potential issue | 🟡 Minor

Update voice-controls.tsx line 343 to use pt-3 pb-safe instead of py-3 pb-safe.

The VoiceControls component uses py-3 pb-safe which causes a Tailwind v4 padding-block cascade issue. The py-3 class sets both padding-top and padding-bottom, then pb-safe attempts to override only the bottom padding, resulting in inconsistent behavior. Use pt-3 pb-safe to apply padding-top and safe-area-aware padding-bottom separately.

bottom padding (pb-safe) can override bottom spacing correctly.
