chore: update lock file to pick up latest @launchdarkly/node-server-sdk 9.10.10

[kinyoklion]

Summary

Regenerated package-lock.json to resolve the latest SDK versions within the existing >= 8.0.0 constraint in package.json. No source code changes.

Key version bumps:

Package	Old	New
@launchdarkly/node-server-sdk	9.2.2	9.10.10
@launchdarkly/js-sdk-common	2.3.1	2.24.0
@launchdarkly/js-server-sdk-common	2.2.2	2.18.3
launchdarkly-eventsource	2.0.1	2.2.0

The lock file was fully regenerated (rm package-lock.json && npm install), so transitive dependencies (express, body-parser, etc.) also received minor/patch bumps.

Review & Testing Checklist for Human

• lockfileVersion changed from 2 → 3: This requires npm 7+. Verify CI and any deployment environments use a compatible npm version — if they use npm 6 or older this will break.
• Transitive dependency https-proxy-agent jumped from ^5 to ^7 (and agent-base from 6.x to 7.x) as a side effect of the SDK update. Confirm there are no proxy-related regressions if the app runs behind a proxy.
• Run the app locally (npm start with an SDK key) and verify the feature flag evaluation still renders correctly on the Bootstrap page.

Notes

• The package.json version constraint (>= 8.0.0) was intentionally not changed — it already permits the latest version; only the lock file was stale.
• The full lock file regeneration means this PR touches more than just the LD SDK lines. A narrower npm update @launchdarkly/node-server-sdk would have produced a smaller diff but may leave other stale transitive pins.
