Allow all HTTP endpoints to fail gracefully

[ra0x3]

• We're currently using a bit of panic/expect logic on web API routes
• The server should not stop if anything goes wrong with an HTTP request
• We should allow all requests to fail gracefully, log errors, and return a generic INTERNAL_SERVER_ERROR

Additional context

• Looks like axum has some type of error handling functionality but not sure how easy it is to use https://docs.rs/axum/latest/axum/error_handling/index.html
