QUA-1806: Correct SAML provider setup instructions

[RafaelOsiro]

Overview

Corrects the SAML provider section of the Single Sign-On setup guide. Engineering (Eric) flagged that the previous instructions listed Entity ID as something the customer sends to Qualytics, but it is actually a Service Provider identifier that Qualytics generates and provides back to the customer. The Assertion Consumer Service (ACS) URL was also missing from the values Qualytics shares.

Key Changes

• Customer sends to Qualytics: Sign-in URL + Signing certificate. The previous table also included Entity ID here, which has been removed (it belongs to the SP side).
• Qualytics provides back: new table listing Entity ID (the SP identifier the customer configures on their IdP) and the Assertion Consumer Service (ACS) URL (the endpoint where the IdP posts the SAML assertion).
• IdP metadata URL or XML: kept as an optional row in the "send" table; clarified that it can be provided instead of the Sign-in URL and Signing certificate separately.

Greptile Summary

This PR corrects the SAML provider setup instructions in the SSO overview guide, fixing a factual error where Entity ID was incorrectly listed as something the customer sends to Qualytics (it is actually a Service Provider identifier that Qualytics generates and shares back).

• Removes Entity ID from the "customer sends to Qualytics" table and places it in a new "Qualytics provides back" table alongside the Assertion Consumer Service (ACS) URL.
• Moves IdP metadata URL or XML to an (optional) row within the customer-sends table, clarifying it can substitute for Sign-in URL + Signing certificate.

Confidence Score: 5/5

Documentation-only change that corrects a factual error in the SAML setup guide; no code paths are affected.

The diff is a targeted documentation correction in a single markdown file. The reorganization of the SAML tables matches the stated intent from engineering: Entity ID moves to the SP-provided section, ACS URL is added, and the metadata row is clarified as optional. The resulting tables are internally consistent and the prose flows correctly.

No files require special attention.

Important Files Changed
