feat: split config into 4 tabs and fix JAR upload 413

Config sub-tabs are now: Monitoring | Traces & Taps | Route Recording | Resources
(renamed from Agent/Infrastructure, with traces and recording as their own tabs).

Also increase Spring multipart max-file-size and max-request-size to 200MB
to fix HTTP 413 on JAR uploads.
