cb9bd2bdf4 feat(server): add API-Key authentication for REST endpoints
server/plugins/Authentication.kt:
- Custom Ktor AuthenticationProvider supporting both X-API-Key header
  and Authorization: Bearer <key> for API-Key validation
- ApiKeyPrincipal data class implementing Principal interface
- 401 Unauthorized with ErrorResponse body for missing/invalid keys

server/plugins/Routing.kt:
- Inventory routes wrapped in authenticate(api-key) block
- Health endpoint remains public (no auth required)

server/src/main/resources/application.conf:
- API key configurable via krisenvorrat.apiKey property
- Environment variable override via KRISENVORRAT_API_KEY

server/tests:
- 7 new AuthenticationTest cases (valid bearer, valid X-API-Key,
  missing key, invalid bearer, invalid X-API-Key, PUT without key,
  health without key)
- All existing ApplicationTest cases updated with bearer auth header

Closes #43

New Gradle module :server (Kotlin/JVM) with Ktor 3.1.2 framework,
configured as an embedded Netty HTTP server.

- Application.kt: entry point using EngineMain for HOCON config
- plugins/Routing.kt: GET /health endpoint returning 200 OK
- plugins/Serialization.kt: ContentNegotiation with kotlinx.json

Configuration:
- application.conf (HOCON): host 0.0.0.0, port 8080, module reference
- logback.xml: SLF4J/Logback console logging

Build config:
- server/build.gradle.kts: Ktor plugin with Fat JAR (server.jar)
- libs.versions.toml: Ktor 3.1.2, Logback 1.5.18 dependencies
- settings.gradle.kts: include(:server)
- :server depends on :shared for common DTO models

Tests: 2 tests (health endpoint, 404 on unknown route) via
Ktor testApplication.
