fix(templates): Pin playwright to base image version in uv Dockerfile template (#1904)

## Summary

The `uv` package-manager branch of the actor Dockerfile template
(`src/crawlee/project_template/{{cookiecutter.project_name}}/Dockerfile`)
doesn't pin Python `playwright` to the version pre-installed in the
Apify base image. When the lockfile resolves to a different `playwright`
version than the base image (currently 1.59.0 vs the base image's 1.60.0
+ chromium-1223), the actor tries to launch a Chromium build that
`/pw-browsers/` doesn't ship and fails with `Executable doesn't exist at
/pw-browsers/chromium_headless_shell-1217/...`.

The pip and poetry branches solve this by sed-rewriting
`playwright==X.Y.Z` to whatever `playwright --version` reports in the
image. The uv branch's `--no-install-package playwright` was supposed to
be the equivalent, but the test's `pip install crawlee
--force-reinstall` (and any user step that touches playwright before the
`uv sync` runs) defeats it.

This fix mirrors the pip/poetry intent for uv:

- **Snapshot** the base image's `playwright --version` in the early `pip
install uv` layer, before `COPY pyproject.toml uv.lock ./` or any
test-injected step can mutate it.
- After `uv sync ... --no-install-package playwright`, check if the
env's playwright still matches; if it has drifted, force-reinstall with
`uv pip install --reinstall --no-deps "playwright==<base-version>"`.
- Guard the reinstall behind a version check so the common case (no
drift) skips the wheel download.

Resolves the 9 failing `uv`-variant scheduled e2e jobs in [run
26082797876](https://github.com/apify/crawlee-python/actions/runs/26082797876)
(`playwright`, `adaptive_beautifulsoup`, `adaptive_parsel` × {httpx,
curl_impersonate, impit}).

Verified against the live `apify/actor-python-playwright:3.13` image:
| Scenario | Before | After |
| --- | --- | --- |
| Real user, no drift | works, but `pip freeze \| grep playwright` check
is brittle | guard short-circuits, no extra work |
| Test injection downgrades playwright to 1.59.0 | mismatched chromium →
crash | reinstall pins to 1.60.0, browsers match |
