"Cache Miss Rates" section doesn't respect organization-based routing

### Environment self-hosted (https://develop.sentry.dev/self-hosted/) ### Steps to Reproduce 1. Use this image: `ghcr.io/getsentry/sentry:819ece03dbdae3b636bbf73b2fa666b51f260630` 2. Enable these feature flags: ```python "organizations:navigation-sidebar-v2", "organizations:navigation-sidebar-v2-banner", "organizations:command-menu-v2", "organizations:insights-session-health-tab-ui", "organizations:insights-modules-use-eap", "organizations:insights-overview-use-eap" "organizations:insights-mobile-screens-module", ``` 3. Go to Insights -> Backend from the web UI, see this result: <img width="3840" height="2039" alt="Image" src="https://github.com/user-attachments/assets/b51275fe-9d92-4fa3-ba1a-e34e1a61d4ac" /> 4. Observe on the "Cache Miss Rates" section (bottom right on the above image), each span name has a link to: `https://sentry.internal.company.com/insights/backend/caches?project=1&transaction=POST%20/account-status` ### Expected Result On self-hosted, the link should be generated with the `useOrganizations()` React hooks. The final link should be: `https://sentry.internal.company.com/organizations/[organization-name]/insights/backend/caches?project=1&transaction=POST%20/account-status` ### Actual Result See step to reproduce. ### Product Area Insights ### Link _No response_ ### DSN _No response_ ### Version 819ece03dbdae3b636bbf73b2fa666b51f260630
