Rename vendors to third parties

Renames the user-facing 'vendor' concept to 'third party' across the
entire codebase. The shared common_third_parties reference table is
unchanged.

Migration. Renames the vendor_category enum, the vendors and
vendor_<entity> tables (contacts, services, compliance_reports,
business_associate_agreements, data_privacy_agreements,
risk_assessments) and their vendor_id columns, the asset_vendors /
data_vendors / processing_activity_vendors junction tables,
generated_documents.vendors_document_id, the webhook_event_type
'vendor:<verb>' values, and the snapshots_type 'VENDORS' value.

Backend. Renames coredata models and SQL queries, probo services,
GraphQL / MCP API surface, console / trust / webhook resolvers and
types, the CLI (prb vendor* -> prb third-party*; pkg/cmd/vendormgmt
-> pkg/cmd/thirdpartymgmt), the document generator, vetting agent
prompts, and the common-third-parties-import command.

Frontend, packages, n8n, e2e. Renames apps/console pages, components,
hooks, routes, dialogs, and tabs; the shared @probo/vendors package
(now @probo/third-parties); the @probo/ui Vendors atoms (now
ThirdParties, VendorLogo -> ThirdPartyLogo); the n8n community node
actions/vendor folder (now actions/thirdParty); and the e2e Go test
suite (console and MCP). Filesystem and URL paths use kebab-case
(third-parties), GraphQL fields and TypeScript identifiers use
camelCase (thirdParty / thirdParties), Go types use PascalCase
(ThirdParty), and human-facing text uses 'third party' with a space.
