docs(partner-portal): Partner Portal documentation (PP-323)

[pap-nazaries]

Context

Adds Prowler Partner Portal user-facing documentation to docs.prowler.com. Prowler Partner Portal is a separate product (partners.prowler.com) for resellers, MSPs and consultants to onboard customers and operate Prowler Cloud tenants on their behalf — until now there was no first-party documentation for it on docs.prowler.com.

Implements epic PP-323 and its 6 child tasks: PP-320, PP-324, PP-325, PP-326, PP-327, PP-328.

Description

Adds 6 new MDX pages and updates docs/docs.json with two new dedicated groups under the "Prowler Partner Portal" name. Partner Portal is a separate product (different audience, URL, API, branding), so its docs are grouped together rather than interleaved inside Prowler Cloud/App.

Pages added:

Task	Path
PP-320 — Overview	docs/getting-started/products/prowler-partner-portal.mdx
PP-324 — Sign-up & sign-in	docs/user-guide/tutorials/partner-portal-sign-up.mdx
PP-325 — Team & roles	docs/user-guide/tutorials/partner-portal-team.mdx
PP-326 — Partner organization	docs/user-guide/tutorials/partner-portal-organization.mdx
PP-327 — Customer onboarding & access	docs/user-guide/tutorials/partner-portal-customer-onboarding.mdx
PP-328 — Branding	docs/user-guide/tutorials/partner-portal-branding.mdx

docs/docs.json adds two groups:

• Getting Started → new Prowler Partner Portal group, between Prowler Lighthouse AI and Prowler MCP Server.
• Guides → new Prowler Partner Portal group at top level, sibling of Prowler Cloud/App, CI/CD, CLI, Providers, Compliance, Cookbooks.

Steps to review

1. Check out the branch and run cd docs && npm install -g mint && mint dev.
2. Open http://localhost:3000 and verify:
   • Getting Started sidebar shows the new Prowler Partner Portal group between Prowler Lighthouse AI and Prowler MCP Server; the Overview page renders at /getting-started/products/prowler-partner-portal.
   • Guides sidebar shows a new top-level Prowler Partner Portal group with 5 entries in this order: Sign-up → Organization → Team → Branding → Customer onboarding.
3. On the Your partner organization page, click the in-text link to Customise Partner Portal branding and verify it resolves without 404 (the only internal cross-link between Partner Portal pages).
4. Optionally check the Mintlify preview deploy posted on this PR by the Mintlify GitHub App.
