Pull request overview

Adds an explicit team-wide storage quota (totalLimitBytes) to the cellsInternal feature-flag config, and updates defaults/docs/tests to reflect the split between team total limit and per-user quota.

Changes:

• Introduce QuotaBytes and extend CellsStorage with optional totalLimitBytes alongside perUserQuotaBytes.
• Update integration/stern tests and Galley integration config to use the new storage quota shape and defaults.
• Update documentation and changelog to describe the new fields and “negative means unlimited” semantics.
