A factory default model, repaired onboarding, and cleaner workspace updates

Choose a stable factory model, create a workspace after signup, recover profile-assigned specialists, and keep miniapp releases aligned across the workspace.

Settings now expose a canonical factory default model, giving workspaces a stable fallback when no custom default has been selected.

New-account onboarding restores account scope before it creates a workspace, fixing a blocker that could strand users immediately after signup. Specialists assigned through profiles appear again, and delegated work persists its complete parent and child lineage for later inspection.

Project and knowledge empty states now share a calmer, centered treatment. Chat timestamps keep their intended size, quick reactions reset predictably and expose better accessibility labels, and desktop tooltips and stray scrollbars lose their distracting chrome.

View-only members no longer see an empty General access card. Logging out remains available on blocker and error pages, and model catalog refreshes use the correct account boundary.

Workspace miniapp releases now converge on the assigned version instead of leaving clients on mixed updates.
