ci(e2e): run a PR's changed e2e tests three times behind a human-approved environment

Adds a required-check candidate that selects the tests/e2e test files a PR added or
modified, boots a stage-mirror stack on the runner (migrations, backend, two gateway
processes behind nginx, Postgres, Jaeger, TLS cluster Valkey), and runs those files
three times with retries off. The run job sits behind the e2e-changed GitHub
environment, so a reviewer approves each run before the OIDC token that reads the
provider keys from AWS Secrets Manager exists. Supersedes #34981

+Every PR that adds or modifies a `tests/e2e/**/test_*.py` file (outside `ui/`, `claude_code/`, and `load/`, which have their own lanes) runs exactly those files three times, with retries off, against a stage-mirror stack booted on a GitHub Actions runner: migrations, a control-plane backend, two gateway processes behind an nginx load balancer, Postgres, Jaeger, and a TLS cluster-mode Valkey, wired the way stage is deployed. A PR that only touches the harness or the stack itself runs the `access_control/` suite as a smoke instead. Three green passes are the bar because the check exists to catch a flaky test before it reaches the release gate, so a red pass is a failure to fix, not a retry candidate. The same stack boots on a laptop with `bash .github/e2e-stack/up.sh`: it reads provider keys from `tests/e2e/.env`, writes the pytest environment to `${E2E_STACK_DIR:-/tmp/litellm-e2e-stack}/stack.env`, every port is overridable through `E2E_*_PORT` variables, and `down.sh` tears it all down

 ### Record and replay
 
 Record/replay scopes to the proxy's provider-bound traffic only. In `E2E_FIXTURE_MODE=record` the harness boots a local provider-edge server, edge-wired tests register their deployments with an `api_base` pointing at it, and every provider call the proxy makes is forwarded verbatim and written to a fixture bundle (default `tests/e2e/.fixtures`, override with `E2E_FIXTURE_DIR`). `E2E_FIXTURE_MODE=replay` runs the same tests against the same live proxy and database, but the edge answers the proxy's provider calls from the bundle instead of the provider, so the run makes zero provider calls and spends nothing while key auth, routing, cost calculation, and spend-log writes all still execute for real. Unset (or `live`) behaves exactly as before the knob existed. Both record and replay need the proxy up; only the provider is taken out of the loop
