Firestore

The issues: Firestore index disappearing after deploy, Firestore deploy failing because "index already exists", deployment failing on installing Firebase CLI, MUI X Date Picker stopped informing about invalid date, warning about unnecessary React useEffect dependency on ref, and toast message unusable for copying.

The issues: Firebase app GitHub Actions deploy failing (IAM_PERMISSION_DENIED), SignatureDoesNotMatch error while fetching file from a bucket, no level config per handler in @datadog/browser-logs, and grep skipping hidden files (fzf-lua+ripgrep in Neovim).
