fix: create missing ip_rate_limit table in init_db #71

[createkr]

Fixed a bug where the attestation endpoint would crash due to a missing ip_rate_limit table definition. \n\n- Miner ID: createker02140054RTC

Nice minimal fix - this addresses the immediate crash path by ensuring ip_rate_limit exists.

One follow-up suggestion before/after merge:

• Consider adding an index aligned to lookup pattern in check_ip_rate_limit:
  • current hot query is WHERE client_ip = ? AND ts >= ?
  • table PK is (client_ip, miner_id), which is not ideal for timestamp-window scans
  • suggested: CREATE INDEX IF NOT EXISTS idx_ip_rate_limit_ip_ts ON ip_rate_limit(client_ip, ts)

That should keep rate-limit checks fast as row count grows.

@Scottcjn Checking the CI failure: "Review Tier Label Gate" failed because of missing labels. I don't have permissions to add labels directly to this repo. Could you please add the appropriate BCOS-L* label to trigger the gate?

CI is failing only on Review Tier Label Gate. Could you please add tier label BCOS-L1? After the label is added, the gate should pass and SBOM/SPDX will run.

CI is currently failing on 'Review Tier Label Gate' because the PR is missing a required BCOS label. Could a maintainer please add one of: BCOS-L1 / BCOS-L2 (or bcos:l1 / bcos:l2) so checks can proceed? Thanks.

I also attempted label assignment here and hit permission restriction (AddLabelsToLabelable).\n\nTo unblock CI, maintainer needs to apply an accepted BCOS tier label (likely BCOS-L1 for this low-risk fix), then Review Tier Label Gate should clear.
