fix: instance detail — correct API response mapping (data.instance, not data)

Root cause: useFetch<InstanceDetail> returns { instance: {...} } but code
used 'const instance = data' instead of 'const instance = data?.instance'.
This meant all instance fields (events, license, metadata) were undefined.

Fix:
- Changed InstanceDetail type to { instance: Instance & {...} }
- const instance = data?.instance ?? null
- Moved instance assignment before meta useMemo
- All subsequent code uses 'events' and 'license' safe accessors
