**Motivations :**
* Remove outdated message that appears after account creation/import
* Clean up dead code and unused translation keys
* Simplify presentation page UX now that key creation/import is available
**Root causes :**
* Message 'Connectez-vous avec Nostr pour créer votre article de présentation' was displayed even when account exists
* NotConnected component and translation keys were no longer needed after implementing key creation/import
**Correctifs :**
* Removed NotConnected component and its message
* Removed presentation.notConnected translation keys from all locale files
* Simplified display to show ConnectButton directly when no pubkey is available
* Added auto-loading of pubkey when account exists but pubkey not yet loaded
**Evolutions :**
* Presentation form now displays immediately when account exists (even if not unlocked)
* Better UX: users can see the form and will get error message if they try to publish without unlocking
**Page affectées :**
* components/AuthorPresentationEditor.tsx
* locales/fr.txt
* locales/en.txt
* public/locales/fr.txt
* public/locales/en.txt
