fix: remove dead SLF4J imports, add NOP binding to target

Remove unused Import-Package: org.slf4j from 4 test bundle manifests:
- com.avaloq.tools.ddk.check.ui.test
- com.avaloq.tools.ddk.test.ui
- com.avaloq.tools.ddk.xtext.test
- com.avaloq.tools.ddk.xtext.test.core

No Java or Xtend source file in the entire DDK codebase references
org.slf4j — these were stale declarations.

Add org.slf4j.binding.nop 1.7.30 to the target platform (from the
same Eclipse Orbit repo that already provides org.slf4j.ext). This
provides the SLF4J 1.7.x StaticLoggerBinder that Xtext's transitive
slf4j.api bundle looks for at runtime, silencing the warning:

  SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
  SLF4J: Defaulting to no-operation (NOP) logger implementation

The binding is only needed in the target platform; no Require-Bundle
is necessary since SLF4J discovers the binding via classpath scanning.
