docs(meet-sso): fix setup-order deadlock in the Meet SSO guide

[Lazare-42]

A bot account that is already covered by the Legacy SSO profile cannot complete its first interactive login — Google routes even the first sign-in to the Meeting BaaS IdP, which only bots can complete. The guide currently orders profile assignment (Step 2) before user preparation (Step 3), so customers following it — especially on the recommended dedicated-domain path, where the whole domain is in scope — hit a deadlock at Step 3.2. This is exactly what happened to Diio (support thread 2026-08-13).

Changes:

• Warn in Step 2 (assignment) and Step 3 (first login) about the ordering constraint, with the temporary-exclusion escape hatch for already-scoped accounts.
• Add an optional "Verifying SSO routing" section documenting the incognito test and its expected outcome: landing on our IdP error page IS the success signal; humans can never complete the sign-in.

Companion PR meeting-baas-v2#415 makes the IdP error page itself say this.

Summary by CodeRabbit

• Documentation
  • Added guidance for completing a bot account’s initial interactive Google Workspace login before enabling Legacy SSO.
  • Documented domain-wide assignment steps and recovery options for accounts already placed in the SSO scope.
  • Added an optional incognito login procedure to verify SSO routing.
  • Clarified that the Meeting BaaS bot error page confirms successful routing.

Walkthrough

The Meet authenticated-bot setup guide now documents the required first Google Workspace login, Legacy SSO assignment timing, recovery for already-scoped accounts, and optional SSO routing verification.

Changes

Meet SSO setup guidance

Layer / File(s)	Summary
Bot login and SSO verification guidance content/docs/api-v2/authenticated-bots/meet/setup.mdx	The guide explains first interactive login requirements, Legacy SSO assignment timing, recovery steps, and verification through the expected Meeting BaaS error page.

Estimated code review effort: 2 (Simple) | ~10 minutes

Mergeability Score: 🟡 Moderate · up to 6e846

The guide still allows customers to assign the SSO profile before the bot’s first login, and its recovery steps do not clearly distinguish group versus organizational-unit assignment; this can preserve the login deadlock or lead to an ineffective fix. The PR is not merge-ready until the ordering, recovery guidance, and dedicated-domain wording are corrected.

Poem

A bunny reads the login guide,
“First hop in, then SSO stride.”
If routing sends the proper sign,
The bot is ready, neat and fine.
No lost hops, no tangled trail—
Clear steps help the meeting sail.

In `@content/docs/api-v2/authenticated-bots/meet/setup.mdx`:
- Around line 191-193: Update the warning callout around the interactive
first-login guidance to distinguish recovery for group-assigned versus
OU-assigned Legacy SSO profiles: remove the profile’s group membership for group
assignments, or move the account to an OU outside the profile for OU
assignments. Require verifying that no effective profile assignment remains and
waiting for assignment changes to propagate before retrying the Welcome flow.
- Around line 176-178: Update the Step 2 instructions to configure the Legacy
SSO profile without assigning it, then explicitly defer assignment until all bot
accounts complete Step 3’s first login. Move the optional routing check to run
only after each account is returned to the SSO scope, while preserving the
existing dedicated-domain exclusion guidance.
- Line 177: Update the scope warning near “Complete each bot account’s first
login” to describe whole-domain assignment as optional: replace the wording that
calls it the recommended dedicated-domain setup with wording such as “if you
choose a dedicated bot-only domain,” while preserving the existing first-login
sequencing guidance.
