Strengthen Attempts to Load Canvas

[thehabes]

Canvas URIs are fetched without adequate error handling. These could cause silent failures or crashes when Canvas URIs don't resolve.

Common Issues Across Files

• No response.ok validation before calling .json()
• vault.get() calls not wrapped in try/catch
• Silent failures - users see broken images with no explanation
• No error logging for debugging production issues
