Settings: don't try to allow NLSes with too-long component names

Browse Source 
* NotificationAccessConfirmationActivity (triggered through CompanionDeviceManager) -> Don't show the dialog, bail out early similarly to other invalid inputs.
* NotificationAccessSettings (from Special App Access) -> No changes, but use the canonical constant now.
* NotificationAccessDetails -> Disable the toggle, unless the NLS was previously approved (in which case it can still be removed).
