fix: disable static resources on --no-ui and clean up stale SpaController routes

- CodeIqApplication: set spring.web.resources.add-mappings=false when --no-ui
  is active, preventing static file serving (index.html, JS, CSS bundles)
- SpaController: replace stale /topology and /flow routes with /graph (matches
  the current Code Graph treemap tab added in 482ca24)
- SpaControllerConditionalTest: add staticResourcesDisabledWhenUiDisabled test
  and spaControllerExplicitRoutesContainGraph test (1449 total, 0 failures)
