Fix theme and sidebar hydration

[miurla]

Summary

• Replace the theme provider with a local implementation that inserts the initial theme script through server-inserted HTML.
• Move theme consumers to the local hook and remove the unused theme package.
• Isolate the sidebar New link in a client component to avoid hydration mismatches at the server/client boundary.

Root Cause

The previous theme package rendered an inline script inside the React tree, which can trigger React 19 script and hydration warnings. The sidebar mismatch came from passing a Next link through a client Slot component across a server component boundary.
