Subject: [PATCH] ci(studio): fetch enough history for paths-filter on push
 events (#49766)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes the master-push failures in the Selfhosted Studio E2E workflow
(e.g. [this
run](https://github.com/supabase/supabase/actions/runs/33383940726))
where all shards die in ~30s at the `dorny/paths-filter` step with:

```
fatal: Not a valid object name <github.event.before>^{commit}
fatal: could not read Username for 'https://github.com': No such device or address
```

On push events, paths-filter diffs against `github.event.before` using
local git. With the default depth-1 checkout that commit usually isn't
present, so the action falls back to a `git fetch` — which runs
unauthenticated because we set `persist-credentials: false`, and GitHub
rejects unauthenticated git fetches from the runner IPs. Whether a job
passed depended on whether the runner's shared git cache happened to
contain the previous master tip, which is why shards fail
nondeterministically and re-runs partially recover.

**Changed:**
- `fetch-depth: 50` on the checkout preceding paths-filter in the three
workflows that run it on push (`studio-e2e-test`, `studio-unit-tests`,
`studio-docker-build`), so the comparison base is always fetched with
the checkout action's own credentials and no fallback fetch happens.
`persist-credentials: false` stays.

PR events are unaffected either way — paths-filter uses the GitHub API
there, not git.

## To test

- CI on this PR passes (PR path exercises the API code path)
- After merge, the next few master pushes run Selfhosted Studio E2E
without the paths-filter step failing

## Summary by CodeRabbit

* **Chores**
* Improved automated build, end-to-end test, and unit test workflows by
ensuring sufficient Git history is available for change detection.
  * Increased reliability of workflow runs triggered by code pushes.
