Other minor redirect URL changes:
- app.urls.* is now deprecated
- redirectToSignOut now sets and preserves after_auth_return_to
- OAuth sign-in after_auth_return_to now carries callback-return context
<!-- CURSOR_SUMMARY -->
---
> [!NOTE]
> **High Risk**
> High risk because it changes OAuth authorization/token issuance,
redirect URL validation, and introduces a new cross-domain handoff
endpoint plus a DB migration linking authorization codes to refresh
tokens, which can affect login/session security and reliability.
>
> **Overview**
> Adds **hosted URL targets** for SDK `urls` resolution (new `{ type:
"hosted" }`/`{ type: "handler-component" }`/`{ type: "custom" }`
options), including env-driven hosted handler domain/template support
and fallback routing for unknown `/handler/*` paths.
>
> Implements a **cross-domain OAuth PKCE handoff**: a new
`/auth/oauth/cross-domain/authorize` endpoint issues one-time
authorization-code redirects bound to the caller’s session refresh
token; authorization codes now persist `grantedRefreshTokenId` and token
issuance reuses/validates ownership of that refresh token. Redirect
planning for `redirectTo*` (and OAuth callback handling) is refactored
into `redirect-page-urls.ts` to preserve `after_auth_return_to` and
cross-domain handoff params.
>
> Tightens redirect safety (e.g., `after_callback_redirect_url` is
validated/whitelisted), centralizes SDK env var reads via `envVars` with
lint enforcement, hardens `EventTracker` startup for partial DOM test
environments, and adds unit/E2E coverage plus a demo page for manual
cross-domain verification.

## Summary by CodeRabbit
* **New Features**
* Cross-domain OAuth PKCE handoff flow (client + server) for hosted
sign-in.
* Hosted handler URL templating with local development domain suffix
support.
* Demo UI page to exercise hosted cross-domain sign-in/out and OAuth
flows.
* Authorization codes now preserve an associated refresh-token id to
support cross-domain exchanges.
* **Bug Fixes**
* Stricter redirect-URL validation and stronger refresh-token ownership
checks.
* More robust event-tracker startup guards in partial DOM environments.
* **Tests**
* New E2E and unit tests covering cross-domain authorize, callback
validation, and handoff flows.

**This PR revolves around the following components**
1. Sequencer - sequences the updates in the internal db
2. Poller - polls for the latest updates to sync with the external db
3. Outgoing Request Handler - essentially a trigger that can make http
requests based on a change in the internal db
4. Sync Engine - syncs with the latest changes from the internal db to
the external db
**What has been done**
- Added a global sequence id for ProjectUser, ContactChannel and
DeletedRow.
- Added the deletedRow table to keep track of the rows that were deleted
across ProjectUser and ContactChannel.
- Added the OutgoingRequest table to keep track of the outgoing requests
- Added function for the sequencer to call to sequence updates
- Added a sequencer that sequences all the changes in the internal db
every 50 ms
- Added a poller that polls for the latest changes in the internal db
every 50 ms, and adds to a queue
- Added a Vercel cron that calls sequencer and poller every minute
- Added a queue that fulfills the outgoing requests by making http calls
(for external db sync, it calls the sync engine endpoint)
- Added a sync engine that uses the defined sql mapping query in the
user's schema to pull in the changes for the user, and sync them with
the external db
- Added tests to test out each functionality
**How to review this PR:**
1. Review the migrations (sequence id, deletedRow, triggers, backlog
sync) (all files created under the migrations folder)
2. Review sequencer
3. Review poller
4. Review the changes in schema
5. Review sync-engine (the function, and it's helper file)
6. Review the schema changes, and query mappings
7. Review the tests (basic, advanced and race, along with the helper
file)
8. Review the changes made in Dockerfile to support local testing using
the postgres docker

> [!NOTE]
> Introduces a cron-driven external DB sync pipeline with global
sequencing, internal poller and webhook sync engine, new DB
tables/functions, config schema/mappings, and comprehensive e2e tests.
>
> - **Database (Prisma/Migrations)**:
> - Add global sequence (`global_seq_id`) and
`sequenceId`/`shouldUpdateSequenceId` to `ProjectUser`,
`ContactChannel`, `DeletedRow` with partial indexes.
> - Create `DeletedRow` (capture deletes) and `OutgoingRequest` (queue)
tables; add unique/indexes.
> - Add triggers/functions: `log_deleted_row`,
`reset_sequence_id_on_update`, `backfill_null_sequence_ids`,
`enqueue_tenant_sync`.
> - **Backend/API**:
> - New internal routes: `GET
/api/latest/internal/external-db-sync/sequencer`, `GET /poller`, `POST
/sync-engine` (Upstash-verified) for sync orchestration.
> - Add cron wiring: `vercel.json` schedules and local
`scripts/run-cron-jobs.ts`; start in dev via `dev` script.
> - Tweak route handler (remove noisy logging) without behavior change.
> - **Sync Engine**:
> - Implement `src/lib/external-db-sync.ts` to read tenant mappings and
upsert to external Postgres (schema bootstrap, param checks,
sequencing).
> - Add default mappings `DEFAULT_DB_SYNC_MAPPINGS` and config schema
`dbSync.externalDatabases` in shared config.
> - **Testing/Infra**:
> - Add extensive e2e tests (basics, advanced, race conditions) for
sequencing, idempotency, deletes, pagination, multi-mapping, and
permissions.
> - Docker compose: add `external-db-test` Postgres for tests; e2e deps
for `pg` types.

### Summary of Changes
We need a way to tell if our email service is working. So, we set up a
route that will be periodically hit by uptime kuma. This route tries to
sign up to stack auth.
Upon signing up, an verification email will be sent. We use resend to
check the inbox and return a success if the email is found.
We use resend to setup a test email domain, and we query that domain to
see if the email has been received. In test environments/dev, we use
inbucket instead. This route also requires a secret token, which can be
configured via `.env` variables.
### Necessary config changes
Note we add several new environment variables which will need to be
populated in prod.
Also, the [config settings for
resend](https://resend.com/docs/send-with-smtp) are as follows:
1. **Host:** `smtp.resend.com`
2. **Port:** `465`
3. **Username:** `resend`
4. **Password:** `<RESEND_API_KEY>`
These may need to be set up in docker to enable emails being sent out to
resend.
To set this up with uptime kuma, follow the steps below:
1. Create a new monitor
2. Set the monitor type to `HTTP(s)`
3. The URL should hit the `/health/email` endpoint.
4. Suggested request timeout is at least 120 seconds. Reading emails
from the resend inbox can take a bit of time.
5. In headers, set the header as below:
```
{
"authorization": "Bearer <STACK_EMAIL_MONITOR_SECRET_TOKEN>"
}
```

## High-level PR Summary
This PR changes the default development ports for several background
services to avoid conflicts. PostgreSQL moves from port `5432` to
`8128`, Inbucket SMTP from `2500` to `8129`, Inbucket POP3 from `1100`
to `8130`, and the OpenTelemetry collector from `4318` to `8131`. All
references across configuration files, Docker Compose setups,
environment files, CI/CD workflows, test files, and documentation have
been updated to reflect these new port assignments. A knowledge base
document has been added to document the new port mappings.
