feat(ext/shared): add Device + FieldHistory types + 8 new message types

Device: name, public_key (hex), added_at.
FieldHistoryView: field_id, field_name, current_value, entries[].
Messages: list_devices, add_device, revoke_device, list_trashed,
restore_item, purge_item, purge_all_trash, get_field_history.

Also adds stub cases in popup-only.ts switch to keep tsc happy until
Tasks 3-5 wire up the real handlers.
