fix: Deep-link Slack settings to the correct anchor

[joshsny]

Problem

In PostHog Code's Slack settings, the Manage in PostHog Web button opened the PostHog Integrations settings page but did not scroll to or highlight the Slack integration — it just landed on the section.

The link used the hash #setting=integration-slack. The PostHog settings scene scrolls to a specific setting via the useAnchor hook, which matches location.hash.slice(1) against an element id directly (<h2 id="integration-slack">). #setting=integration-slack matches no element id, so no scroll/highlight happened. The full settings scene has no URL handler that reads a setting= hash param on load.

(For reference, the originally-reported 404 was a separate, earlier issue — the section path was already corrected to project-integrations in #2477; this PR fixes the remaining hash.)

Changes

Changed the deep-link hash from #setting=integration-slack to the bare-anchor form #integration-slack.

This matches exactly what PostHog's own urls.settings(section, settingId) helper generates (via combineUrl, a value-less hash key) and what useAnchor resolves to the Slack integration heading. The section path stays project-integrations, the canonical alias of environment-integrations where the integration-slack setting lives.

How did you test this?

• Verified against the PostHog web source (SettingsMap.tsx, settingsSceneLogic.ts, settingsLogic.ts, Settings.tsx, useAnchor.ts, urls.ts) that integration-slack is the real setting id, that project-integrations is the canonical section, and that useAnchor scrolls to the bare #integration-slack anchor while #setting=... does not resolve on load.
• No automated tests added — this is a one-line URL string change with no existing test coverage for the link.
