Disable all suppression fields as a group

We did not previously extend our full disabling logic to all suppression
fields. Now, when we determine that alert suppression is
invalid/disabled, we disable all those relevant fields together.

This commit accomplishes the above, and also factors out some shared
boolean logic into the more general `areSuppressionFieldsDisabled`
boolean, which is shared by most of these fields.
