Task instructions for process tasks

New Features: Added support for embedded task instructions on all embedded task types that support performers: User, Manual, Send, Receive, and Business Rule. Embedded task instructions inherit permissions from the root process. Workspace tables now display tasks with embedded instructions in the same manner as subprocesses. These are filtered under the “Tasks” category. Improvements: Introduced a plain-text “Description” field to embedded task instructions. Automatically populated from the legacy task Description in the properties panel. Global Tasks now support a dedicated Description field. Deprecations & Migrations: Removed the ability to embed Scribe/Knowby/Tango/Guidde via the properties panel. Existing tasks using these embeds have been migrated to embedded task instructions. Removed the ability to add embeds from the properties panel.
