[Fix] Backfill missing command menu items conditional availability expression (#20852)

## Description

Following [report in
discord](https://discord.com/channels/1130383047699738754/1498690477044793386/1506602927412744242)

Some command menu items were showing to all users because they had no
conditional availability expression, whereas users did not actually have
access to the page or feature behind. For instance: "Go to Admin panel",
"Go to AI settings", "Send email" etc.

/>


## Fix

- Add conditional availability expressions
- Backfill expressions for existing workspaces as they are stored in db
(commandMenuItems table)
