🤖 fix: restyle section headers and rename section chat copy

[jaaydenh]

Summary

Restyle sidebar section headers to remove the tinted background and left color bar, replacing them with colored section-name text and left indentation. Also rename section-related copy from "workspace" to "chat".

Background

The section header design previously used a subtle background tint and a left color bar to indicate the section color. The new design simplifies this by applying the section color directly to the section name text, removing visual clutter. The "workspace" terminology in section-specific UI is also updated to "chat" for consistency with the product direction.

Implementation

SectionHeader.tsx:

• Removed backgroundColor, borderLeftWidth, borderLeftColor inline styles from the header container
• Added pl-3 (0.75rem) left indentation
• Applied style={{ color: sectionColor }} to the section name text (removed text-foreground class)
• Renamed plus button: aria-label → "New chat in section", tooltip → "New chat"

ProjectSidebar.tsx:

• Empty-state copy: "No workspaces in this section" → "No chats in this section"

sections.test.ts:

• Updated aria-label selector to match new string
