chore(obs): retire the DP-side real-SLS smoke test (moved to CP)

[moonming]

What

Removes the DP-side real-Aliyun-SLS smoke test (mod smoke in crates/aisix-obs/src/sink/sls.rs — sls_smoke_putlogs_and_readback + its readback/response_contains helpers) and its aliyun sls smoke (real) CI job.

Why

The real-credential SLS validation has moved to the control plane (api7/AISIX-Cloud#709) as a full-chain e2e: configure an aliyun_sls exporter via cp-api → boot a live DP → fire a real chat → read the request-event back from the real logstore. That exercises the actual user path (dashboard/cp-api config → kine → DP → upstream → SLS), which a DP-isolated smoke test cannot. The CP is where the whole feature integrates, so it's the right home for the real-credential check.

The org's SLS CI secrets (ALI_SLS_AK_ID / ALI_SLS_SK) have already been migrated from this repo to the CP.

Scope / safety

• Pure deletion: 2 files, 205 lines, all removals. No production code touched.
• The removed module was #[cfg(test)] and #[ignore]-gated — it never ran in the normal suite. Its helpers (readback, response_contains, env) were used only within it.
• cargo clippy -p aisix-obs --all-targets -- -D warnings is clean — the production helpers the smoke test referenced (base_url_for, now_unix_secs, AliyunSlsSink) remain used by the sink + the regular unit tests, so nothing is orphaned.
• Nothing needs: the removed CI job.
• The DP's mock-SLS L2 e2e (sink mechanics: v1 signature / lz4 block / protobuf wire, against the in-stack mock-sls) is unaffected and remains the DP-side coverage.

Summary by CodeRabbit

• Tests
  • Removed Aliyun SLS integration smoke tests from the CI pipeline and repository.
  • Updated e2e test documentation to clarify that live endpoint validation is handled by the control-plane full-chain e2e, not this repo.

📝 Walkthrough

Walkthrough

Removed the sls-smoke CI job and the corresponding #[cfg(test)] mod smoke in the SLS sink; updated the Aliyun SLS e2e test comment to state real endpoint acceptance is validated by the control-plane full-chain e2e.
