Concurrency audit: I18n::translate() returns a const char* pointing INTO strings_, and loadLanguage()
clears/rebuilds strings_ on the main thread at a language switch. The EmbeddedDaemon state/monitor callback
builds its status strings via TR() off the main thread, so a concurrent language switch could free the
map node out from under that pointer — a use-after-free data race.
- Add a shared_mutex guarding strings_: loadLanguage() takes it exclusively for the whole clear+rebuild
(its helpers loadBuiltinEnglish/overlayTranslations are called only from there and don't lock, so no
recursion); a new translateCopy()/trCopy() takes a shared lock and returns an owned std::string.
- The lock-free translate()/TR() stays for main-thread UI (same thread as the writer, so never races).
- The four daemon-state setDaemonStatus(TR(...)) calls in the monitor callback now use util::trCopy(...).
Synchronization only; no fund-path call touched. Threading fix — clean build + ctest; the race is runtime-only.

Two of the systemic error-surfacing foundations from the UX audit:
- util::friendlyRpcError() maps the common raw daemon/JSON-RPC errors
(warming up / -28, locked / -13, method-not-found / -32601, insufficient
funds, unreachable node) to short translated guidance with a next step,
falling back to the trimmed raw text. Wired into the send (money) path: the
toast shows the friendly cause, the overlay keeps the raw text below it for
diagnostics. The helper is reusable for the remaining raw-error sites.
- Toasts now pause their auto-dismiss while hovered and ellipsize over-long
text with the full message in a hover tooltip, instead of hard-clipping it
mid-word (durations were already lengthened earlier).

Many strings are used directly as printf/ImGui format strings, and translations
are loaded from user/installer-modifiable JSON with no validation. A translated
value that drops or changes a conversion specifier would be passed to printf with
mismatched varargs (undefined behavior) on a wallet screen.
overlayTranslations() now compares each translated value's argument signature
against the English source and keeps English on mismatch. Also adds the
send_status_unconfirmed string used by the deferred-send-result path.
