Fixes from @melpike's feedback.
Keep the Windows tab visible when Windows MDM is off rather than hiding
it, and disable Create hidden admin with a tooltip pointing at Windows
MDM, matching how the macOS tab already behaves.
- Extracted `TurnOnMdmTooltipWrapper` to reduce code duplication
Reword the password-policy error fleetd reports so it reads as
sentences. The whole string is generated by Fleet, not by Windows, and
it is now shown to admins verbatim in the Show managed account tooltip.
Left-align that tooltip.
