goblin: remove Settings Import identity (replace-current) flow

Owner correction: importing an existing identity belongs at first-run
(onboarding, restored in the previous commit), not in Settings. The
Settings > Identity "Import identity" row was the destructive
replace-the-current-identity action, redundant now that add-identity and
the identity switcher cover bringing in keys non-destructively. Removes
the settings row, the inline ImportState/import_nsec_ui flow, and the
five now-unused settings keys (import_identity, import_identity_title,
import_blurb, identity_replaced, now_using) across all eight locales.

Wallet::import_nostr_identity stays: the onboarding import panel calls
it. The shared settings.* strings the onboarding panel reuses
(importing, import_failed, import_nsec_hint, backup_read_failed,
choose_backup_file, backup_password_hint, import_btn, cancel, close)
also stay. Drift + call-site tests green.
