[Fall 26] Project analytics config page #88

Context

Juno has analytics config CRUD on the gateway. The dashboard has no analytics UI. This ticket is config only — event viewing is a separate ticket.

Relevant API routes (api-gateway)

Base: JUNO_BASE_URL (local http://localhost:8888). Docs: /docs. Expect an API key (Bearer); environment comes from the key.

@Controller('analytics/config')

What to build

Under /projects/[projectId]:

• Add Analytics to the project sidebar (can link here even if events ticket isn’t done)
• Page to view / create / update / delete this project’s analytics config (server + client keys, environment implied by key)
• Clear empty state when no config exists (“set up analytics”)
• Always be explicit about project — don’t silently use the wrong one (juno#226)

Out of scope

• Listing / charting click/visit/input/custom events → separate ticket
• Logging events from the dash

Done when

• From a project page you can create and manage analytics config
• Missing config shows a sane empty state
• Wrong-project / auth failures surface clearly
• Sidebar entry exists

Notes

• Local: Juno + dash .env with JUNO_API_KEY
• Prefer existing juno-sdk helpers if present
