feat(block): Add data enrichment block (#4774)

* feat(enrichment): workflow Enrichment block + /api/tools/enrichment/run

Add a generic Enrichment workflow block that runs a code-defined enrichment
(Work Email, Phone Number, Company Domain, Company Info, …) and returns its
outputs — usable in workflows, not just tables.

- New internal endpoint POST /api/tools/enrichment/run (checkInternalAuth +
  contract) runs the same runEnrichment provider cascade; injects the
  workspace's hosted/BYOK key via executeTool.
- New tool enrichment_run posts to it and surfaces hosted-key cost on the
  output so the workflow logging session bills it.
- New block blocks/blocks/enrichment.ts generated from the enrichment registry:
  operation dropdown = enrichments, per-enrichment conditional inputs, union of
  conditional outputs. New registry entries appear automatically.
- EnrichmentRunContext.tableId/rowId made optional (workflow path has no row).
- Register tool + block; bump api-validation route baseline; add EnrichmentIcon
  and generated docs page.

* chore: re-trigger CI

* refactor(enrichment): share mapFieldType helper between block and tool

* fix(enrichment): reserved output keys (matched/provider) win over enrichment outputs
