CommandMenuItem overridable entity (#21486)

## Context
Second PR of the overridable-entities track (after #21436 for views):
command menu items become overridable so that edits on non-owned items
are stored as overrides instead of mutating the row, and
deletion/deactivation becomes reversible.

 ## What this does

- `CommandMenuItemEntity` now extends
`OverridableEntity<CommandMenuItemOverrides>` (adds `isActive` +
`overrides`). All editable properties are overridable for now (to
discuss).
- **Update**: mutations on a command item not owned by the caller
(standard items) are written into `overrides`; reads merge them in the
DTO. The command palette edit mode (pin,
reorder, shortLabel) now preserves standard values, "Reset label to
default" gains true post-save semantics.
- **Delete**: protected items are deactivated (`isActive = false`)
instead of deleted; custom items still hard-delete.
- **Object deactivate/enable toggle**: now flips `isActive` on the
command item (merged into the main migration call) instead of
delete/recreate; a create-if-missing fallback covers legacy deactivated
objects.
- **Front**: inactive command items are filtered out of the palette
selector.
