refactor(atmn): rename tierBehaviour → tierBehavior

[joejohnson123]

American English spelling for consistency with the rest of the SDK.

Changed

• tierBehaviour → tierBehavior in SDK types, transforms (apiToSdk, sdkToCode, sdkToApi), and typegen
• API wire format (tier_behaviour) is unchanged — only the user-facing SDK property is renamed
