i18n(wallet): translate the migrate-to-seed UI + document it in CLAUDE.md

Route the migration modal (renderSeedMigrationDialog) through TR() — 32 new
keys (30 mig_* plus the previously-untranslated seed_migrate_button/
tt_seed_migrate), reusing existing common keys (cancel/close/refresh/
seed_backup_save*). Format-arg strings go through snprintf(buf, TR(...), v)
so the %.8f/%d specifiers stay in the (validated) translations; plain
strings use "%s", TR(...) to avoid -Wformat-security.

Translated into de/es/fr/ja/ko/pt/ru/zh — additive only (972 -> 1004 keys
per language, format specifiers verified preserved); CJK subset font rebuilt.

CLAUDE.md gains a "Seed phrase & migrate-to-seed" section documenting the
hd-transparent-keys daemon dependency, -usemnemonic, the backup screen, and
the Phase 1 (isolated create) / Phase 2 (sweep + Confirming gate + adopt)
flow that was live-verified on mainnet.
