feat(pyegeria,dr-egeria): add Data Standards types (Egeria PR #9300)

[dwolfson]

Summary

Adds SDK and Dr.Egeria support for the new Data Standards types from
odpi/egeria#9300:

• pyegeria: Investigation classification pair on ProjectManager
  (set/clear_project_as_investigation), NamingStandardsVocabulary
  classification pair on GlossaryManager
  (set/clear_glossary_as_naming_standards_vocabulary), and the four new
  DataScope/DataLens datetime properties (dataValidityStartTime/EndTime,
  dataCoverageStartTime/EndTime) documented in classification_explorer.py
  and governance_officer.py sample bodies.
• Dr.Egeria: registered Investigation/NamingStandardsVocabulary in
  curation.py's CLASSIFICATION_METHODS/CURATION_CLASSIFICATION_CLIENTS,
  added the 4 new Classify/Declassify commands to
  commands_curation_compact.json via the Spec Editor's REST API, and
  regenerated basic/advanced templates via refresh_specs.
• docs/dr_egeria_manual.md updated to document the additions.

Caveats

Endpoint/property shapes were taken directly from the egeria PR #9300 diff on
GitHub, since this checkout's .http ground truth files haven't been updated
for this PR yet. validate_compact_specs currently fails its live-server
OM_TYPE check for both new types since the target server doesn't have the new
type archive deployed yet — re-verify against a live server once it does.

Test plan

• pytest -m unit passes
• pytest tests/micro-tests/test_gen_report_specs.py passes
• Dispatcher registration verified: all 4 new commands route to
  CurationClassifyProcessor
• Live-server verification once the new type archive is deployed
