Upgrade adapter-utils to canary with getConfigSchema type support

The UI wasn't surfacing config parameters because getConfigSchema wasn't
part of the ServerAdapterModule interface in adapter-utils >=0.3.0. The
canary release (2026.411.0-canary.8) adds ConfigFieldSchema,
AdapterConfigSchema, and getConfigSchema to the type. This removes the
local type augmentation workaround and the unsafe `as ServerAdapterModule`
cast, letting TypeScript properly validate the schema contract.
