style(toast): reposition to bottom-center, solid bg, larger text, longer duration

TODO.md

@@ -19,6 +19,7 @@
 
 ## UI
 - [x] **admin header** — replace "Déconnexion" text link with SVG sign-out icon (accessible via `aria-label` + `.sr-only` span)
+- [x] **toast styling** — repositioned to bottom-center; solid `--bg-secondary` background; font bumped to `--step-0`; padding increased; visible duration extended to ~6.35 s; enter animation slides up from bottom
 
 ## Bug fixes
 - [x] **smtp-test.php** — wrap `SmtpRelay::send()` in `try/catch SmtpSendException` so SMTP delivery failures (e.g. 550 recipient rejected) surface as a proper flash error instead of an uncaught exception/silent crash
