fix: remove ipx dependency (now indirect via @netlify/images)

[Copilot]

Summary

Removed ipx as a direct dependency since it's now consumed indirectly through @netlify/images@1.2.5. The refactoring to use @netlify/images for image proxy handling (completed in earlier commits) made the direct dependency obsolete.

Changes:

• Removed ipx: "3.1.1" from package.json dependencies
• Updated package-lock.json accordingly

Test Coverage:

• 3 integration tests validate image functionality:
  • Remote image transformations (format conversion, sizing, quality)
  • Local image transformations with SSR
  • Image CDN endpoint not shadowed by v2 functions

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• dl.deno.land
  • Triggering command: /usr/local/bin/node node /home/REDACTED/work/cli/cli/bin/run.js dev --offline -p 35827 (dns block)
  • Triggering command: /usr/local/bin/node node /home/REDACTED/work/cli/cli/bin/run.js dev --offline -p 40655 (dns block)
  • Triggering command: /usr/local/bin/node node /home/REDACTED/work/cli/cli/bin/run.js dev --offline -p 42237 (dns block)

  • Triggering command: /usr/local/bin/node node /home/REDACTED/work/cli/cli/bin/run.js dev --offline -p 42237 (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
