Update storage settings

Replaces the account-level storage lifecycle settings applied to newly uploaded fal CDN files. Omitted or null fields are cleared (reset to the system default), so always send the full desired configuration.

ACL rules referencing users that do not exist are dropped. The response reflects the settings actually saved, so verify it contains the rules you sent.

These are the same settings that the per-request X-Fal-Object-Lifecycle-Preference header overrides on individual requests.

Authentication: Required. The API key must have the account:settings:write permission.
