F8 (security). Two related fixes to how the wallet decides whether an RPC target is
safe to send Basic-auth credentials to:
- isLocalHost() was matching any host that merely *starts* "127." via
rfind("127.",0)==0, so "127.evil.com" (and "127.0.0.1.attacker", "127.300.0.1",
"1270.0.0.1") were misclassified as loopback and treated as local. It now uses a
strict isExactIPv4Loopback() parser: exactly four 0-255 dot-separated octets with
the first == 127. localhost / ::1 / [::1] handling is unchanged.
- A remote rpchost over plain HTTP (no rpctls=1) previously only produced a
dismissible warning and then sent rpcuser:rpcpassword in cleartext, where a
local-network MITM could capture them. tryConnect() now REFUSES that connection
(clear status line + one-time notification, no creds sent) unless the user opts in
explicitly with rpcallowplaintext=1 in DRAGONX.conf (new
ConnectionConfig::allow_plaintext_remote, parsed in parseConfFile; policy in the
new allowsPlaintextRemote()). Local/embedded daemons and rpctls=1 remotes are
unaffected.
BREAKING: a wallet configured for remote plaintext RPC will stop connecting until
rpcallowplaintext=1 (or rpctls=1) is added to DRAGONX.conf. Must be called out in the
release notes. The Settings-toggle UI is deferred (the conf-key opt-in is the recovery
path; see docs/daemon-startup-hardening.md).
Adds testIsLocalHost and testAllowsPlaintextRemote to test_phase4.cpp; one i18n key
(English) added to i18n.cpp.

Three verified daemon-startup edge-case fixes centered on the config/params
filesystem path:
- F7: new non-throwing Platform::ensureDirectory(dir, outError) with one
consistent "Cannot create <dir>: <reason>. Check permissions / free space."
message. Replaces the unchecked/throwing create_directories sites at main.cpp
(pre-init: log + Windows MessageBox + return 1), connection.cpp's
autoDetectConfig (was the *throwing* overload -- could raise an uncaught
filesystem_error through its callers; now sets the new
ConnectionConfig::dir_error), and both app.cpp daemon-dir sites (surface via
daemon_status_ + return false). The primary connect path (app_network.cpp)
checks dir_error and shows it instead of mislabelling it "waiting for config".
embedded_resources.cpp already checked its error_code, so it is left as-is.
- F6: verifySaplingParams() now hash-verifies each param against its pinned
canonical SHA-256 (source of truth: scripts/build-lite-backend-artifact.sh)
instead of only checking existence, so a truncated / corrupt-but-present param
is rejected up front rather than failing later on a shielded operation. A
<params_dir>/.sapling_verified marker keyed on size:mtime avoids re-hashing
~48MB on every startup. Logic extracted to the injectable, unit-testable
verifySaplingParamsIn(dir, digests); reuses util::sha256Hex (no new hash impl).
- F5: startEmbeddedDaemon() now checks extractEmbeddedResources()'s return and
the previously-dropped copy_file error_code in the daemon-binary fallback loop,
aborting with a clear status (sb_daemon_extract_failed / sb_daemon_files_failed)
instead of failing opaquely at spawn. An absent source file stays non-fatal.
Adds testPlatformEnsureDirectory and testVerifySaplingParams to test_phase4.cpp.
i18n keys added to i18n.cpp (English source of truth); the res/lang/*.json
back-fill via add_missing_translations.py is deferred to a single run at the end
of the batch. Progress tracked in docs/daemon-startup-hardening.md.

- rpc_client: wipe the plaintext "user:password" temporary with sodium_memzero after
base64-encoding it into the auth header (std::string doesn't zero its buffer on
destruction).
- connection: the auto-generated DRAGONX.conf holds rpcuser/rpcpassword in plaintext but
was written with the default umask (often world-readable 0644). Restrict it to owner
read/write after creation so another local user can't read the credentials.
- app: copying a seed phrase / private key to the clipboard now arms an auto-clear —
App::copySecretToClipboard() copies the secret and, after 45s, wipes the clipboard IF it
still holds that secret (compared via a stored hash, never the plaintext). Wired into the
lite first-run wizard's seed Copy and the Settings export-secret Copy, with a
"clipboard auto-clears in 45s" notice. pumpSecretClipboardClear() runs each frame.

- Replace hardcoded IP addnodes with node.dragonx.is, node1–4.dragonx.is
in both daemon launch params and auto-generated DRAGONX.conf
- Add max_connections setting (persisted, default 0 = daemon default);
passed as -maxconnections= flag to dragonxd on startup
- Show blocks/sec in status bar during sync with exponential smoothing
(e.g. "Syncing 45.2% (12340 left, 85 blk/s)")
- Fix z_importwallet to use full path instead of filename only
- Add rescanBlockchain() method that restarts daemon with -rescan flag
- Track rescan progress via daemon output parsing and getrescaninfo RPC
- Display rescan progress in status bar with animated indicator when starting
- Improve dark theme card contrast: lighter surface-variant, tinted borders, stronger rim-light
