fix(sider): pass correct collapsed state to Title component

[AmateurMind]

Problem

Users reported that ThemedTitle custom text was not working when used inside Sider's Title prop (issue #7239).

Root Cause

The mobile drawer implementation was passing collapsed={false} instead of the actual siderCollapsed state to custom Title components across all UI libraries.

Solution

Changed collapsed={false} to collapsed={siderCollapsed} in all UI libraries:

• packages/mui/src/components/themedLayout/sider/index.tsx (line 434)
• packages/antd/src/components/themedLayout/sider/index.tsx (line 227)
• packages/chakra-ui/src/components/themedLayout/sider/index.tsx (line 275)
• packages/mantine/src/components/themedLayout/sider/index.tsx (line 228)

Impact

✅ Custom Title components now receive correct collapse state on all screen sizes
✅ ThemedTitle custom text works correctly in responsive layouts
✅ All existing tests pass
✅ No breaking changes introduced

Fixes #7239

Hey @AmateurMind, thanks for the contribution!

collapsed={false} in the mobile drawer is intentional. The mobile drawer always opens at full width (200-240px), so the title should always show in expanded form (icon + text). siderCollapsed tracks the desktop sidebar state — if a user collapses the sidebar on desktop then switches to mobile, your change would show a collapsed title (icon only) inside a 200px wide drawer, which is broken UX.

Also, issue #7239 is about custom Title components not rendering at all — that's unrelated to the collapsed prop value. The collapsed prop only toggles the text visibility ({!collapsed && }), it doesn't control whether the custom component renders. I wasn't able to reproduce the original issue either. Closing this PR — thanks again for looking into it!
