## Changes
- Replaces plan ID-based chart gating with entitlement-based checks
across all observability pages (database, auth, realtime,
edge-functions)
- Adds requiredPlan display field so the upsell shows the correct target
plan (e.g. "Upgrade to Team" for disk throughput, not just "Upgrade")
- Decouples database-charts.ts from Organization Plan, now accepts
pre-computed entitlement flags instead
### Note on `requiredPlan`
The entitlement system currently tells us whether a user has access, but
not what plan they need to get access. `requiredPlan` is a frontend-only
display hint. Ideally the backend entitlement response would include a
minimumPlan field so we can remove this hardcoded mapping. For now, this
is a pragmatic workaround to avoid misleading upsell copy (e.g. a Free
user seeing "Upgrade" for a Team-only feature and landing on Pro).
## Testing
### Database
- Head to `/project/_/observability/database` with an Org on the Free
Plan and assert that the Disk throughput is gated.
