Matt Rossman 8aeacc6152 feat(assistant): disable Braintrust tracing for EU regions and DPA signers (#44504)
**Changes**

- Extracted tracing conditional to an `isTracingAllowed` helper with
unit tests (the function is simple but sensitive hence the extra testing
precaution)
- Disables Braintrust tracing for projects in EU database regions
(region prefix `eu-`) to address GDPR data residency concerns
- Disables Braintrust tracing for orgs whose owners have signed the
previous DPA, as a stopgap during the 30-day notice period for the
updated DPA that adds Braintrust as a subprocessor
- Refactored `org-ai-details.ts` → `ai-details.ts`, splitting
`getOrgAIDetails` into separate org and project helpers to cleanly scope
the EU-region check at the project level

DPA check uses the newly added `/documents/dpa-signed` endpoint from
https://github.com/supabase/platform/pull/31060. This PR includes
regenerated `api.d.ts` and `platform.d.ts` from running `pnpm codegen`
in `packages/api-types` to get type safety on this new endpoint.

Note tracing is still yet to be activated in production, this is a
preparatory step.

**To verify**

Send a chat message and check for the `x-braintrust-span-id` response
header on `POST /api/ai/sql/generate-v4` — it should be absent for
DPA-signed orgs or EU-region projects, and present otherwise.

If you have access to the Braintrust dashboard, you can also verify
whether logs are produced or not in the Assistant project there.
