Fix infinite redirect loops on two blog posts

[Yndira-E]

Description

• Two blog posts were rendering empty (or 404ing), with the browser reporting an infinite redirect loop:
  • /blog/2023/05/integrating-modbus-with-node-red/
  • /blog/2026/03/rethinking-edge-ais-core-orchestration/
• Root cause: PR Prune stale redirects, move redirect handling to Nuxt #5540 moved legacy 11ty redirects for old, differently-cased URLs into nuxt/redirects.ts. Nitro's route matching is case-insensitive by default, so each of these rules also matched its own lowercase canonical URL, redirecting it to itself — an infinite loop that aborts navigation before the page ever renders.
• Removed both stale entries from nuxt/redirects.ts and re-added them to netlify.toml instead. Netlify's edge redirects match exact case, so the old capitalized URLs still 301 to the canonical lowercase URLs, without colliding with them.
• Audited the rest of nuxt/redirects.ts for the same pattern (a key case-insensitively equal to its own to, or colliding with another key) — no other instances found.

Test plan

• Visit both post URLs locally (npm run dev), confirm they render normally now.
• Visit both post URLs in the deploy preview, confirm they render normally.
• Visit the old capitalized-casing URLs in the deploy preview (netlify.toml redirects only run through Netlify's own layer, not plain nuxt dev, can't be checked locally without netlify dev, confirm they 301 to the canonical URL instead of looping or 404ing.
