Remove dead Pipedrive chat widget from docs footer

[AlexKantor87]

Summary

• Removes the Pipedrive LeadBooster chat widget script from docs.kosli.com/layouts/partials/docs/footer.html.
• We migrated off Pipedrive to HubSpot almost a year ago, but the LeadBooster loader was still embedded on every docs page — silently pinging an abandoned Pipedrive workspace (companyId 7960593) on every visit and rendering nothing visible (verified at https://docs.kosli.com/).
• Side effect: unblocks Netlify deploys. The checklinks plugin has been timing out (ETIMEDOUT) on https://leadbooster-chat.pipedrive.com/assets/loader.js from Netlify's build infra, blocking every deploy. Removing the script tag means the URL is no longer in the built site.

Test plan

• Netlify deploys docs-main successfully after merge
• Visit https://docs.kosli.com/ — no chat bubble (same as before, since the widget wasn't rendering anyway)
• DevTools → Network: no request to leadbooster-chat.pipedrive.com

Static Analysis

All checks pass:

• go build ./... — clean
• go vet ./... — clean
• go mod tidy — no drift in go.mod / go.sum

(Expected, since this PR only touches an HTML partial.)

Code Review

Change: Removes 2 lines from docs.kosli.com/layouts/partials/docs/footer.html — the inline Pipedrive LeadBooster config script and its accompanying <script src="...loader.js" async> tag.

Verdict: LGTM — this is a clean, safe removal of dead third-party code.

Details:

1. Correctness — The removed script was configuring and loading Pipedrive's LeadBooster chat widget (companyId: 7960593). Since the team migrated to HubSpot ~a year ago and the widget renders nothing on the live site, this is purely dead code. No other file in the repo references pipedriveLeadboosterConfig or LeadBooster.

2. Side effects — Positive only. Removes an unnecessary external network request to leadbooster-chat.pipedrive.com on every docs page load, and unblocks Netlify deploys that were timing out on that URL.

3. File hygiene — The old file was missing a trailing newline (the Pipedrive <script> was the last line without \n). After this removal, the file correctly ends with a newline. Nice fix.

4. Security — Removing a third-party script from an abandoned vendor workspace is a security improvement — it eliminates a vector where a compromised/repurposed Pipedrive asset could inject code into the docs site.

5. No test impact — This is a Hugo HTML partial; no Go tests are affected.

No issues found. Clean PR, well-scoped, good PR description with clear test plan.
