From the app-wide robustness audit (calibrated to the import-key dialog). These
are the safety-critical fixes; several could cost users funds:
- Backup/export false success (FUND LOSS): exportAllKeys pre-seeded a header, so
a keyless result (the usual case when the wallet is encrypted+locked) still
looked non-empty and backupWallet wrote a private-key-less file and reported
"Backup saved". Now exportAllKeys returns an exported count; backupWallet and
the export-all dialog refuse to write / report success on 0 keys, disclose the
count, flag partial results as INCOMPLETE, and the backup dialog confirms
before overwriting an existing file (+ trims the path).
- Bootstrap: fail CLOSED — refuse to install an unverified multi-GB archive when
no checksum is published (was `return true`), mirroring the xmrig/daemon updaters.
- Restore-from-seed: require a valid BIP39 word count (12/15/18/21/24) with a live
"should be 24 words — you have N" hint instead of accepting any non-empty text.
- Encryption passphrase: detect leading/trailing whitespace and BLOCK with a
warning (not a silent trim, which would change the passphrase and lock the user
out).
- Receive payment QR: emit the canonical `drgx:` scheme with a URL-encoded memo
via a new shared util::buildPaymentUri (the request-payment dialog now routes
through it too, so they can't diverge); the old "dragonx:" + raw memo was
unparseable by the wallet's own scanner.
Also clamps the receive "Recent Received" list to the 4 most recent (companion to
the recent-lists commit).

- rpc_client::callRaw: a daemon error object is no longer assumed to carry a string
"message" — a malformed error now yields a clean "RPC error: <dump>" instead of throwing
a json type-exception from .get<std::string>().
- sendTransaction (full-node): add a single-flight guard so a rapid double-click can't issue
two z_sendmany before the first returns its opid. The lite path already guarded this; the
send form guards it in the UI, but the controller entry point now does too.
(#9 from the audit was mostly false positives on verification — all popen sites already
null-check and the xmrig download FILE* path has no throwing calls. The payment-URI
checksum idea was dropped: the send flow already checksum-validates the recipient before
broadcasting, and tightening the parser would reject the placeholder addresses the existing
test relies on; added a comment noting this is format-only by design.)
