Reduce padding in mobile chat input area

[ngoiyaeric]

User description

The mobile chat input area had excessive padding that occupied too much vertical space on the screen. This change reduces the padding at multiple levels (container, form, and input field) and adjusts the minimum height of the text area on mobile. It also removes a hardcoded left padding that was intended for a desktop-only attachment button, resulting in a more compact and centered layout for mobile users.

Main risk is the CSS deletion in globals.css: removing .mobile-icons-bar-content .icon-button may unintentionally regress icon sizing/hover/tap targets if that selector is still in use. The ChatPanel padding changes look coherent, but consider making trailing padding (pr-12) responsive as well to avoid wasted space on mobile if the trailing controls differ.

Additional notes (3)

• Maintainability | app/globals.css:190-190
  You removed .mobile-icons-bar-content .icon-button styles from globals.css. If these icons exist elsewhere (not only inside the deleted .mobile-chat-input layout), their sizing/hover behavior will silently change and could regress touch targets on mobile.

Given the PR description, it sounds like the attachment button moved to an icons bar—this makes it more likely that these styles are still relevant. If the icons bar is now styled via Tailwind classes in the component, this is fine; otherwise, this deletion is risky without updating the icons bar markup/styles in the same PR.

• Compatibility | app/globals.css:190-190
  The container .mobile-chat-input-area uses align-items: center; with reduced vertical padding. With a multiline TextareaAutosize (up to 3 rows on mobile), centering can cause odd vertical alignment (e.g., textarea appears vertically centered instead of naturally aligned to the top/baseline as it grows).

This can create a subtle layout jump when the input expands from 1 → 2 → 3 rows.

• Readability | components/chat-panel.tsx:240-248
  Mobile now removes pl-14 (good for reclaiming space), but the textarea still has pr-12 on both mobile and desktop. If the send button / trailing controls differ between mobile and desktop (or move into an icons bar), pr-12 may be excessive on mobile and create a visually off-center input.

Also, the desktop-only pl-14 suggests a leading control; on mobile that leading control is gone, so consider making right padding responsive in the same way to match the actual trailing controls.

Summary of changes

What changed

• Reduced vertical padding in the mobile chat input container by updating .mobile-chat-input-area from padding: 10px to padding: 4px 10px in app/globals.css.
• Removed unused mobile-specific CSS:
  • Deleted the .mobile-chat-input block and related nested styling (including absolute-positioned icon buttons).
  • Deleted .mobile-icons-bar-content .icon-button styles.
• Adjusted mobile ChatPanel spacing in components/chat-panel.tsx:
  • Mobile <form> now uses tighter padding (pb-1 pt-0 instead of pb-2 pt-1).
  • Removed the conditional mobile-chat-input class from the wrapper <div>.
  • Updated textarea classes to be mobile/desktop explicit:
    • Mobile: min-h-10 pl-4 pt-2 pb-1 and removed the old pl-14 desktop-centric spacing.
    • Desktop: retains min-h-12 pl-14 pt-3 pb-1.
