refactor(storage): rename "expiration policy" to "lifecycle policy"

Renames the noun phrase that names the policy object — the section
heading in the create/edit bucket modals, the file preview panel
tooltip title, the empty-state copy in the archived / trash views, and
the internal ExpirationPolicySection component — to "lifecycle policy",
matching S3's own terminology.

Preserves verb / action-form uses of expire/expiration where they
describe what happens when the policy fires (ExpirationSentence,
ExpirationExplainer, ExpirationMode, version_expiry_days, "Noncurrent
version expiration" label, etc.) — those name the action, not the
policy.
