Fix OAuth app name typo: 'Daatcore' should be 'Datacore'

[crtahlin]

Summary

The Google OAuth consent screen shows the app name as "Daatcore" instead of "Datacore".

Steps to reproduce

1. Run Google Calendar OAuth setup
2. Observe the consent screen shows "Daatcore"

Expected behavior

App name should be "Datacore"

Priority

Low - cosmetic issue only, doesn't affect functionality.

Fix

Update the app name in Google Cloud Console → APIs & Services → OAuth consent screen.

Triage 2026-09-06: cannot be fixed from the repository — the app name lives in Google Cloud Console → APIs & Services → OAuth consent screen. Left open as the owner's action; close after the rename.
