…n config

`_filter_headers` previously used a hardcoded sensitive-header tuple and a
`send_default_pii`/`use_annotated_value` toggle. It now delegates to
`_apply_key_value_collection_filtering` from `sentry_sdk.data_collection`,
so header scrubbing respects the new `data_collection.http_headers.request`
allowlist/denylist/off configuration.

Cookie and set-cookie headers are
always redacted regardless of mode. Drops the now-unused
`use_annotated_value` parameter from all call sites.

Work to scrub cookies in a more granular way will be tackled as part of
PY-2581/#6741.

…ures

The new lambda_functions_with_embedded_sdk fixture directories were
missing the .gitignore that the other fixtures use to keep everything
except index.py untracked. As a result, certifi and urllib3 packages
installed by the test setup got committed, and ruff failed CI linting
against them since they're unmodified third-party code.

Add the missing .gitignore to each new fixture directory and remove
the committed vendored packages; they are regenerated automatically at
test time via `uv pip install --target`.

…tarlette, litestar, starlite

Extends the granular cookie collection controls (data_collection.cookies)
to _wsgi_common, starlette, litestar, and starlite, matching the behavior
already used elsewhere. Falls back to should_send_default_pii() when
data_collection is not configured for cookies.

HTTP "Cookie" and "set-cookie" headers will continue to be completely filtered
with the "[Filtered]" value.

…de is off

Previously the async request extractors attached an empty cookies dict
when the data_collection cookies mode was off, while sync route handlers
omitted it entirely. Make all integrations consistent by not attaching
the cookies field at all when filtering yields no cookies.
