User Story

As an admin, I want the SitePolicies policy to support an EphemeralStorage field, so that I can remove all site data for the matched site when the isolated site session ends.

Acceptance criteria:

- EphemeralStorage (boolean): Clears all site data for the matched site when the isolated site session ends. 

Implementation notes:
- https://firefox-admin-docs.mozilla.org/reference/policies/sitepolicies/
- https://firefox-admin-docs.mozilla.org/reference/policies/sanitizeonshutdown/
- When the isolated session ends, the browser purges cookies, localStorage, IndexedDB, cache, etc. for that site automatically. Session-end trigger is last tab for the origin closed / overlaps with SanitizeOnShutdown.
  - one proposal was to reuse Private Browsing mode for this.
  - Optionally, consider if an admin could enforce a time-to-live for the session (e.g. auto-delete after X hours / days of inactivity)

Out of scope:
- New site-matching syntax; constraints reuse the existing SitePolicies site-matching mechanism.

When SitePolicies is configured to open domains in containerized tabs with ephemeral set to true, all site data for the matched site is cleared when the isolated site session ends—that is, after its last tab is closed.

Verified using Firefox Enterprise 158.0b5 (20261006191302) and Firefox Enterprise 159.0a1 (20260930034337).
