### Context
We're looking at implementing plan pricing. While doing so, we
encountered a problem with Stripe.
**Problem:** when we run a stripe operation (purchase), the product info
is encoded as part of the stripe metadata request. Stripe encodes
metadata as key-value pairs, and the [value has a limit of 500
chars](https://docs.stripe.com/metadata#data). We do this because once
we run the stripe operation, stripe fires a webhook event which is
caught by our stripe webhook handler syncStripeSubscriptions. This gets
the stripe metadata info from the event and then updates our db in
prisma.
### Summary of Changes
We add a `ProductVersion` table and only pass the `productVersionId` via
stripe metadata instead of the whole product json. This
`productVersionId` is created by hashing the `productJson`. Since the
same product may be ordered differently without being intrinsically
different, we add a helper function for ensuring a canonical order to
the json. We also pass tenancy id and product id to the table.
Since there are existing subscriptions which used to pass the
productJson via metadata, we ensure backwards compatibility.

---
> [!NOTE]
> **High Risk**
> Touches authentication and OAuth token/authorize flows and changes how
client requests are validated, so regressions could cause widespread
login/client-access failures. Also includes a data migration that alters
effective security posture for existing projects.
>
> **Overview**
> Adds a **project-level toggle**
(`project.requirePublishableClientKey`) to control whether client
requests/OAuth flows must include a publishable client key, including a
DB migration that backfills existing projects to require it.
>
> Backend auth now treats the publishable client key as *optional when
allowed*, introducing a public sentinel (`__stack_public_client__`) and
returning a new specific error
(`PUBLISHABLE_CLIENT_KEY_REQUIRED_FOR_PROJECT`) across smart request
auth + OAuth `authorize`/`callback`/`token` endpoints.
>
> Dashboard and SDKs update key generation/display and request
construction to handle missing publishable keys, expose an advanced
toggle on the Project Keys page, and extend internal config overrides to
support a new `project` level; E2E/tests and schema fuzzing are expanded
accordingly, and CI adds a forward-compat migration check job when
back-compat fails.

### Context
Some of our users' emails were getting stuck in sending. The long delays
in processing the retries caused a vercel function timeout.
### Summary of Changes
We refactor the low level email sending functions to remove the retry
logic there. We kick it up to the email queue step. Additionally, we
flag emails to be retried when they encounter issues but leave it for a
future iteration to actually perform the retry. We perform an
exponential backoff with a random component to decide when they have to
be retried. We also make some small adjustments to the queuing function
to not queue skipped emails.
When an email fails to send during the sending function, we check to see
if it is a retryable error or not. Some errors are transient and trying
again may succeed while others indicate deeper issues. If it is
retryable, and the max number of retry attempts hasn't been reached, we
set `nextSendRetryAt` to a time determined by an exponential backoff
calculation function. When the queuing function looks for emails to
queue, it doesn't just pick up the `SCHEDULED`. emails whose
`scheduledAt` time <= `NOW()`, but also those emails whose
`nextSendRetryAt` time <= `NOW()`. What this means in practice is that
one iteration of the `email-queue-step` will mark emails as retryable
while another iteration will perform the retry. This should be cleaner
and prevent long delays in the `email-queue-step` process due to
retries. This also makes it easier to scale up the number of retries if
need be.

**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

/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

### Context
Recently, a user raised [this
issue](https://github.com/stack-auth/stack-auth/issues/1144), which
indicated that `tokenOverrides` were not being respected/used in the
`getUser()` function. If we trace the flow through this function, we see
`this._getSession -> this._getOrCreateTokenStore -> _createCookieHelper
-> createCookieHelper -> createNextCookieHelper -> await rscHeaders()`.
What this means is that even when a `requestLike tokenOverride` was
passed, we would not end up using it because the `createCookieHelper`
call occurs before the extant override checking logic in
`getOrCreateTokenStore`, and the `createCookieHelper` didn't check the
override but only the default `tokenStoreInit`. This caused the error to
propagate up.
### Summary of Changes
We check the `tokenStoreOverride` in the `createCookieHelper` function
now, preventing this issue from happening. We also add extra test
coverage to verify that overrides are respected, and don't overwrite the
default token store.
### Out of Scope Discussion
The original issue was raised with a `bun` runtime running `next.js`
code. There seems to be some incompatibility between `bun 1.3.8` and
`nextjs 15+`, not just with our backend but with fetching and working
with responses from any `nextjs` server.
