(Found via #94027)

Describe the problem

When there are many databases, the database list page refuses to load with an error.
The specific limit seems to be environment-dependent. For example on my machine I encounter this limit at ~450 databases.

To Reproduce

1. start cockroach demo with the changes from sql: new functions crdb_internal.generate_test_objects and .gen_rand_ident #94027
2. generate 1000 databases, e.g. via select crdb_internal.generate_test_objects('{"names":"mydb._._","counts":[1000,0,0],"name_gen":{"noise":false}}'::jsonb);
3. navigate to db console -> databaes

Observe: page is broken (see screenshot below)

Expected behavior

Database list should always display regardless of database count.
