fix(file-system): expose entry creator

[puemos]

Problem

Desktop clients need the stable creator identity already stored on file-system entries to enforce personal ownership correctly.

Changes

• Serialize the existing created_by relation with UserBasicSerializer.
• Regenerate the core API type and cover desktop list responses.

How did you test this code?

• uvx ruff check posthog/api/file_system/file_system.py posthog/api/file_system/test/test_file_system.py
• uvx ruff format --check posthog/api/file_system/file_system.py posthog/api/file_system/test/test_file_system.py
• OPT_OUT_CAPTURE=1 uv run --package hogli hogli build:openapi-types
• The focused Django test was collected but could not run locally because Postgres is unavailable in this environment.

Automatic notifications

• Publish to changelog?
• Alert Sales and Marketing teams?

Docs update

No documentation change needed; this exposes an existing model field in the API response.

🤖 Agent context

Autonomy: Human-driven (agent-assisted)

Codex traced the desktop file-system contract and implemented the smallest serializer and regression-test change. No repo-provided skills were invoked.

✅ Eager graph — within budget

How much code each root ships on the eager path — downloaded and parsed before the surface is interactive. Measured from the esbuild output chunks (post-tree-shake, static imports only); lazy import() / React.lazy chunks are not counted.

✅ Toolbar bundle — eager 2.18 MiB within budget

What the toolbar ships to customer pages, measured from the esbuild output (minified, post-tree-shake). The eager set is the entry plus everything statically imported from it — fetched before any feature runs; deferred chunks load lazily. The eager guardrail is 5.72 MiB. Each output file must also stay below 10 MB, where CloudFront stops compressing it. The module boundary is enforced separately by check-toolbar-graph.

🦔 Hogbox preview · ❌ build failed

The preview didn't come up for commit 25daf8a. See the build log for the failing step. It'll retry on the next push.

_{Previews are optional and never block merging. A failure here is often a hogland or tailnet hiccup rather than anything in your PR, so the check stays green and this comment is the status.}
