ui: Database page shows incorrect zone config

[thtruo]

Describe the problem

First reported by @fabiog1901

The Databases Page in DB Console is displaying the incorrect zone config value for the number of replicas. The right hand side panel does not seem to update to display the table's actual number of replicas.

To Reproduce

Affects 21.1.6

• Edit zone configs for a table to be 5 replicas (default is 3)
• ✅ Notice that SHOW RANGES FROM TABLE tabname; shows 5 replicas
• ✅ Notice that the Databases Page in DB Console shows 5 replicas when you look at the the "zone config" section (towards the bottom)
• ❌ Notice that the Databases Page in DB Console incorrectly shows 3 replicas on the right hand side

cc @kevin-v-ngo while triaging, I realize that since this lives in the Databases Page it's owned by the SQL Observability team. Is this something you feel comfortable prioritizing in your team's backlog? For context, Cluster UI resolved a related issue early this year that might be a helpful reference for the SQL Obs team https://github.com/cockroachdb/cockroach/issues/57896
