chore(docs): DSPX-2959 add Java/JS shorthand enum updates and version badges

- Update JS imports to use barrel exports from @opentdf/sdk instead of
  deep proto paths
- Update policy.mdx Java example to use PolicyEnums shorthand constants
- Update policy.mdx JS example to use enum values instead of strings
- Add SdkVersion badges with NEXT placeholders to code samples
  (replace with actual versions once SDK releases ship)

Note: Java code_samples/java/ files are pulled from the java-sdk repo
at build time via remote-content plugin. They will update automatically
once javaSdkVersion is bumped in docusaurus.config.ts after the
java-sdk release containing opentdf/java-sdk#357.
