feat: update error pages

[achingbrain]

Updates error page styling in line with boxo.

• Updates project config to use react to generate error pages
• Adds blake2-256 to helia config
• Uses collecting logger to show helia logs in debug info
• Shows which providers we tried to fetch blocks from and how (e.g. bitswap vs trustless gateway vs something else)

Fixes #875
Fixes #876

Change checklist

• I have performed a self-review of my own code
• I have made corresponding changes to the documentation if necessary (this includes comments as well)
• I have added tests that prove my fix is effective or that my feature works
