Follow-up to #3796, which bumped the slack-client axios paths but left
posthog-node's transitive `axios@1.15.1` in place.
`posthog-node` 4.17.1 → 5.35.6. v5 drops the axios dependency entirely
(it's now fetch-based via `@posthog/core`), so posthog's old axios path
disappears. With #3796 already on main (webapp + d3 references on
`@slack/web-api@7.16.0`), nothing else pins the old line, so the
now-dead `axios@>=1.0.0 <1.15.0` override is removed and axios resolves
to a single patched `1.16.1` repo-wide. This closes the remaining axios
advisories.
Compat: the webapp's usage in `telemetry.server.ts` (`new PostHog(key, {
host })`, `.identify`, `.groupIdentify`, `.capture`) is all object-form
API that v5 preserves; `pnpm run typecheck --filter webapp` passes.
Node: posthog-node v5 requires Node `^20.20.0 || >=22.22.0`. We run
20.20.0 in dev (`.nvmrc`), CI, and the published Docker image
(`node:20.20-bullseye-slim`), so we're compliant.
