feat(wallets): show "HD wallet" instead of "?" when the seed flag is unreadable

When a row is probed as an HD wallet (has hdseed/hdchain records) but the
mnemonic flag can't be read — e.g. the rare tier-1 byte-scan fallback on an
unusual BDB variant or a >256 MB file — it now shows a neutral "HD wallet"
badge (ICON_MD_ACCOUNT_TREE) rather than a bare "?", which read as alarming.
"Unknown" (?) is reserved for a scan that couldn't even establish it's HD
(incomplete, no HD marker seen). Both still yield to the Lock badge when
encrypted. Seed/legacy/hd/unknown remain mutually exclusive.

Adds wallets_badge_hd / _hd_short strings (EN source + all 8 languages,
additive) and rebuilds the CJK subset font for the new glyphs.
