Update all dependencies to latest versions and fix compatibility issues

**Motivations:**
- Keep dependencies up to date for security and features
- Automate dependency updates in deployment script
- Fix compatibility issues with major version updates (React 19, Next.js 16, nostr-tools 2.x)

**Root causes:**
- Dependencies were outdated
- Deployment script did not update dependencies before deploying
- Major version updates introduced breaking API changes

**Correctifs:**
- Updated all dependencies to latest versions using npm-check-updates
- Modified deploy.sh to run npm-check-updates before installing dependencies
- Fixed nostr-tools 2.x API changes (generatePrivateKey -> generateSecretKey, signEvent -> finalizeEvent, verifySignature -> verifyEvent)
- Fixed React 19 ref types to accept null
- Fixed JSX namespace issues (JSX.Element -> React.ReactElement)
- Added proper types for event callbacks
- Fixed SimplePool.sub typing issues with type assertions

**Evolutions:**
- Deployment script now automatically updates dependencies to latest versions before deploying
- All dependencies updated to latest versions (Next.js 14->16, React 18->19, nostr-tools 1->2, etc.)
