Improve Resource UX

[fmhall]

We want resources like the Echo x402 AI router to be more easily accessible from x402scan. Right now the UX looks like this:

There are a number of things we might be able to improve:

• Showing the required parameters at the top
• Allowing resource registration to add metadata / defaults about certain params (Allow uploading of openapi spec for resources #97 is related)
• Make the optional parameters collapsible by default (?)

Think on it for a bit and use your best judgement! Don't just throw Cursor / Claude Code at it :)
