build(cloudflare): revert custom worker entrypoint to standard Astro build output

[saifulalomdev]

📝 Description

This PR standardizes the Cloudflare deployment configuration pipeline to resolve architectural runtime and middleware execution issues on the edge.

Key Changes:

• Astro Config Simplification: Dropped the custom workerEntryPoint tracking pointing to ./src/worker.ts within astro.config.mjs, reverting the Cloudflare adapter back to its native, fully-managed compilation lifecycle mode.
• Wrangler Entrypoint Correction: Updated the "main" execution entry point inside wrangler.jsonc to correctly target Astro's compiled production bundle pathway (dist/_worker.js/index.js). This aligns the deployment with standard Cloudflare Pages advanced build requirements and eliminates deep routing initialization errors.
