Address PR review feedback: fix whitespace, add Javadoc, update copyright year

- Revert whitespace-only changes in AbstractCIBase.java
- Add complete Javadoc for new public API methods (isSnoozed, snooze, doSnooze,
  getSnoozedAdministrativeMonitors, setSnoozedAdministrativeMonitors)
- Remove extraneous blank line in getRequiredPermission Javadoc
- Update copyright year from 2025 to 2026 in snooze.js and snoozeForm.properties
