[Deprecation] `jruby-puppet.master-*` Config Aliases

[silug]

Summary

jruby-puppet schema still includes deprecated master-* directory keys in favor of server-* keys.

Evidence

• src/clj/puppetlabs/services/jruby/jruby_puppet_schemas.clj:70 comment: deprecated in favor of server-* and marked for removal.
• src/clj/puppetlabs/services/jruby/jruby_puppet_core.clj:196 still maps master-* keys as fallback inputs.
• src/clj/puppetlabs/services/jruby/jruby_puppet_core.clj:205 re-populates master-* keys from server-* values for compatibility.

Proposed OpenVox Server 9 Change

• Remove master-conf-dir, master-code-dir, master-var-dir, master-run-dir, master-log-dir from schema and compatibility mapping.
• Support only server-* keys.

Compatibility / Risk

• Medium risk for deployments still using legacy master-* config keys.
• Migration is mechanical key rename.

Implementation Notes

• Add config validation errors for legacy keys.
• Update docs/examples and dev config templates.

Acceptance Criteria

• master-* aliases are no longer accepted in jruby-puppet config.
• Runtime config path uses only server-* values.
• No stale schema comments referencing old removal timelines remain.

Suggested Tests

• Config schema tests for supported/unsupported keys.
• JRuby service initialization tests using only server-* settings.
