## About the changes
Variants are now stored in each environment rather than in the feature
toggle. This enables RBAC, suggest changes, etc to also apply to
variants.
Relates to [roadmap](https://github.com/orgs/Unleash/projects/10) item:
#2254
### Important files
- **src/lib/db/feature-strategy-store.ts** a complex query was moved to
a view named `features_view`
- **src/lib/services/state-service.ts** export version number increased
due to the new format
## Discussion points
We're keeping the old column as a safeguard to be able to go back

## What
This PR fixes a bug where fetching a feature toggle via the
`/api/admin/projects/:projectId/features/:featureName` endpoint doesn't
validate that the feature belongs to the provided project. The same
thing applies to the archive functionality. This has also been fixed.
In doing so, it also adds corresponding tests to check for edge cases,
updates the 403 error response we use to provide clearer steps for the
user, and adds more error responses to the OpenAPI documentation.
## Why
As mentioned in #2337, it's unexpected that the provided project
shouldn't matter at all, and after discussions internally, it was also
discovered that this was never intended to be the case.
## Discussion points
It might be worth rethinking this for Unleash v5. Why does the features
API need the projects part at all when features are unique across the
entire instance? Would it be worth reverting to a simpler feature API
later or would that introduce issues with regards to how different
projects can have different active environments and so on?
### Further improvements
I have _not_ provided schemas for the error responses for the endpoints
at this time. I considered it, but because it would introduce new schema
code, more tests, etc, I decided to leave it for later. There's a
thorough OpenAPI walkthrough coming up, so I think it makes sense to do
it as part of that work instead. I am happy to be challenged on this,
however, and will implement it if you think it's better.
### Why 403 when the project is wrong?
We could also have used the 404 status code for when the feature exists
but doesn't belong to this project, but this would require more (and
more complex) code. We also already use 403 for cases like this for
post, patch, and put. Finally, the [HTTP spec's section on the 403
status code](https://httpwg.org/specs/rfc9110.html#status.403) says the
following (emphasis mine):
> The 403 (Forbidden) status code indicates that the server
**_understood the request but refuses to fulfill it_**. A server that
wishes to make public why the request has been forbidden can describe
that reason in the response content (if any).
>
> If authentication credentials were provided in the request, the server
considers them insufficient to grant access. The client SHOULD NOT
automatically repeat the request with the same credentials. The client
MAY repeat the request with new or different credentials. However, **_a
request might be forbidden for reasons unrelated to the credentials_**.
As such, I think using 403 makes sense in this case.

This commit changes the format of a playground feature's `strategies`
properties from a list of strategies to an object with properties
`result` and `data`. It looks a bit like this:
```ts
type Strategies = {
result: boolean | "unknown",
data: Strategy[]
}
```
The reason is that this allows us to avoid the breaking change that
was previously suggested in the PR:
`feature.isEnabled` used to be a straight boolean. Then, when we found
out we couldn't necessarily evaluate all strategies (custom strats are
hard!) we changed it to `boolean | 'unevaluated'`. However, this is
confusing on a few levels as the playground results are no longer the
same as the SDK would be, nor are they strictly boolean anymore.
This change reverts the `isEnabled` functionality to what it was
before (so it's always a mirror of what the SDK would show).
The equivalent of `feature.isEnabled === 'unevaluated'` now becomes
`feature.isEnabled && strategy.result === 'unknown'`.

* task: Ban changes to variants through feature
After adding the new `/variants` endpoint for features we now have a way
to access control adding/modifying variants, so the /:featureName
endpoint should no longer allow editing/adding variants.
This removes variants as a known field from the featureMetadata schema
and tells joi to stripUnknown, thus making sure we never include
variants in the initial creation or future update calls.
For the old features v1 API we allow it to declare that it has already
validated the data coming with its own schema, so we should use the data
we get from it. Thus keeping the old v1 functionality intact

Add a new .../:feature/variants API
This adds
- `GET /api/admin/projects/:projectId/features/:featureName/variants` which returns
```json
{ version: '1', variants: IVariant[] }
```
- `PATCH /api/admin/projects/:projectId/features/:featureName/variants` which accepts a json patch set and updates the feature's variants field and then returns
```json
{ version: '1', variants: IVariant[] }
```
- `PUT /api/admin/projects/:projectId/features/:featureName/variants`
which accepts a IVariant[] and overwrites the current variants list for the feature defined in :featureName and returns
```json
{ version: '1', variants: IVariant[] }
- This also makes sure the total weight of all variants is == 1000
- Validates that there is at least 1 'variable' variant if there are variants
- Validates that 'fix' variants total weight can't exceed 1000
- Adds tests for all these invariants.
