Adds new and expanded test suites across client and server to cover the
OAuth 2.1 scope system, MCP session manager, collab service, unified
memories helpers, OIDC service, budget slice, and OAuth authorize page.
Also extends SonarQube coverage exclusions to include bootstrapping files
(migrations, scheduler, main.tsx, types.ts) that are not meaningfully
testable.
* add test suite, mostly covers integration testing, tests are only backend side
* workflow runs the correct script
* workflow runs the correct script
* workflow runs the correct script
* unit tests incoming
* Fix multer silent rejections and error handler info leak
- Revert cb(null, false) to cb(new Error(...)) in auth.ts, collab.ts,
and files.ts so invalid uploads return an error instead of silently
dropping the file
- Error handler in app.ts now always returns 500 / "Internal server
error" instead of forwarding err.message to the client
* Use statusCode consistently for multer errors and error handler
- Error handler in app.ts reads err.statusCode to forward the correct
HTTP status while keeping the response body generic
