feat(integrations): add support for Tracify

[murphy-con]

Summary

• Adds the generic Tracify Analytics API-key provider, safe GET credential verification, connection configuration, logo, and connection documentation.
• Adds Tracify to the provider catalog and generated documentation metadata.
• Publishes generated metadata for 8 GET retrieval Action functions and 4 full Sync functions.

Companion PR

• Depends on feat(templates): add Tracify Analytics templates integration-templates#669 for the Tracify template-function source implementations.

Validation

• npm run test:providers
• npm run docs:generate
• npx --yes mintlify@4.2.883 broken-links from docs/
• Provider-flow metadata, generated snippets, SVG/XML, whitespace, and independent fast review passed.

Scope

• Tracify Analytics only; no Events API and no provider-side export-job creation.
