fix(schematics): switch from minecraft-schematics.com to Planet Minecraft

minecraft-schematics.com has Cloudflare WAF blocking POST requests to
its AJAX search endpoint, making automated search impossible. Switched
to Planet Minecraft which has server-rendered search results and direct
schematic download URLs.

Also added browser stealth settings (custom user-agent, webdriver flag
hiding, AutomationControlled disable) and Cloudflare challenge detection
to all Playwright functions.
