💡 What: Replaced sequential database queries with a concurrent Promise.all in the admin stats route.

🎯 Why: In serverless environments like Cloudflare D1, sequential db.prepare(...).first() calls create a significant N+1 latency bottleneck because each statement requires a discrete HTTP request over the network. Since the file, alias, user, and secret stats queries are completely independent, they should be executed in parallel.

📊 Impact: Reduces total database network roundtrip latency for this endpoint from the sum of all 4 queries to just the duration of the longest individual query. Preserves existing fault tolerance by catching individual query errors so one failure doesn't reject the entire batch.

🔬 Measurement: Monitored the total response time of the /api/admin/stats endpoint. Ensured that pnpm test, npx playwright test, and pnpm run build all succeed without regressions.

Replaced four sequential `await db.prepare(...).first()` calls in the admin stats route (`src/app/api/admin/[[...slug]]/route.ts`) with a single `Promise.all` containing the individual promises. This executes the independent scalar queries concurrently instead of sequentially, reducing total database network latency. Used `.catch()` on each promise to ensure fault tolerance is preserved.
