docs: add Organizations & Permissions section under AI builder [ENG-10395]

[adhami3310]

New docs/ai_builder/organization/ section (11 pages) documenting organizations and permissions end to end:

• Overview, Members & seats, Roles & permissions, Managing project access, Custom roles
• Verified domains, Single sign-on (SSO)
• Deployment approvals, Audit logs, Moving projects & apps, Bring your own cloud

Also wires the section into the AI builder docs sidebar and cross-links from hosting/adding-members and hosting/billing.

Content is sourced from the shipped flexgen org/permission model (org roles Admin/Manager/Member, project roles Viewer/Editor/Admin plus custom roles). Screenshots are live on the CDN under docs-preview/organization/….

Greptile Summary

This PR adds a complete "Organizations & Permissions" documentation section (11 new pages) under the AI Builder docs, wires it into the sidebar, and adds cross-link alerts in two existing hosting pages.

• Eleven new .md pages cover the full org/project permission model: overview, members & seats, roles & permissions, project access, custom roles, verified domains, SSO, deployment approvals, audit logs, moving projects/apps, and bring-your-own-cloud.
• The sidebar (ai.py) gains a new "Organization" group referencing all 11 pages; item.py adds "Sso" → "SSO" to the acronym normalization map so the sidebar label renders correctly.
• hosting/adding-members.md and hosting/billing.md each receive a short info alert redirecting readers to the new section.

Confidence Score: 5/5

Safe to merge — pure documentation addition with no runtime logic changes.

All changes are Markdown content and two small Python additions (a sidebar group and an acronym entry). The permission tables and cross-links are internally consistent across the 11 new pages. No runtime code is modified.

No files require special attention. The pre-existing commented-out Integrations block in ai.py was already noted in a previous review cycle.
