Show total snippet count per column in header 💻

File: client/src/components/Board/Column.jsx

Column header shows task count but
never shows how many code snippets
are saved across all tasks 💀 fr!!

Fix: calculate total snippets in column:
const totalSnippets = tasks.reduce(
(acc, task) => acc + (task.snippets?.length || 0), 0
)

{totalSnippets > 0 && (

</> {totalSnippets}

)}
