[Due for payment 2026-08-19] [M3] Migrate Workspace Avatar usages

[mountiny]

Problem

Call sites still pass type={CONST.ICON_TYPE_WORKSPACE} to the monolithic Avatar, keeping workspace forking logic in the facade.

Solution

Migrate all workspace avatar call sites to import and use AvatarWorkspace directly. Remove the workspace branch and type prop handling from Avatar/index.tsx once complete.

Acceptance criteria

• All ICON_TYPE_WORKSPACE Avatar usages migrated (~10 call sites)
• AvatarWorkspace exported from @components/Avatar
• No remaining workspace logic in facade
• Unit/UI tests updated
