Search user-added wallet folders RECURSIVELY (bounded: depth/hit/visit caps,
skip_permission_denied, no symlink-follow, node-junk + node-subtree pruning);
the datadir stays top-level. r.dir is each file's real parent so Open/import
resolve subdir wallets. Auto-suffix the import destination on a name collision.
Add util/wallet_file_probe.h: read encryption/seed/shielded flags straight off
a wallet.dat WITHOUT loading it — validate the Berkeley DB btree magic, then a
bounded streaming byte-scan for the length-prefixed record markers the daemon
writes (mkey -> encrypted; hdseed/hdchain -> seed/HD; zkey/sapzkey -> shielded).
Reads no key material. The Wallets dialog shows Encrypted / Seed / Legacy badges,
plus an Unknown badge when a large file couldn't be fully scanned (so absence of
a lock never falsely reads as unencrypted). Unit-tested + validated read-only
against real wallets.
