fix: correct enrichment doc paths, CLI name, and broken link

[mftnakrsu]

What

Fixes several user-facing references in the enrichment docs and runtime messages that point to names/paths which don't exist, so anyone following the docs hits a wrong command or a missing file.

Changes

• toolbox/enrichment/README.md
  • CLI name: kcenrich → kcagent. The binary is kcagent (src/agent/main.ts → cac.cac('kcagent'), package.json bin.kcagent) and the enrich command is invoked as kcagent enrich (already used later in the same README, line 26). kcenrich does not exist anywhere in the package.
  • Demo cleanup: bq rm -r ${DEMO_CLOUD_PROJECT}:demo-dataset → :demo_ecommerce. The demo creates demo_ecommerce; demo-dataset is never created, so the documented cleanup would not remove the demo dataset.
• agents/enrichment/README.md
  • Broken relative link [docs/sharepoint-setup.md](../docs/sharepoint-setup.md) → (docs/sharepoint-setup.md). The ../docs/ target resolves to agents/docs/sharepoint-setup.md, which doesn't exist; the file lives at agents/enrichment/docs/sharepoint-setup.md. This matches the correct link already used earlier in the same file (line 75).
• agents/enrichment/docs/sharepoint-setup.md
  • 5× python3 toolbox/enrichment/... → python3 agents/enrichment/.... The setup script and agent runner live under agents/enrichment/ (scripts/setup_sharepoint.py, src/agent_runner.py); toolbox/enrichment/ is the unrelated TypeScript package and has no such files.
• agents/enrichment/src/agent_runner.py, agents/enrichment/src/tools/sharepoint_tools.py
  • The runtime "no Microsoft credentials" messages instruct users to run toolbox/enrichment/scripts/setup_sharepoint.py; corrected to agents/enrichment/scripts/setup_sharepoint.py so the printed guidance matches the real path.

Notes

Documentation / help-text only — no behavior change. The two Python edits change only string literals in user-facing messages (verified with py_compile).
