Scheduling reliability and user management improvements

This release improves scheduling reliability across overnight shifts, date changes, daylight saving time, and actual working times. It also brings more dependable user management, clearer email confirmation, and better push notification troubleshooting.

Scheduling reliability

• Scheduling is more reliable for overnight shifts, date changes, daylight saving time, and actual start and end times.
• Activities now stay inside the correct shift window when events are edited, copied, duplicated, or created from templates.
• Invalid activities are skipped or adjusted more gracefully instead of breaking event copy and template workflows.
• Shift reminders and digest emails now use each person's actual working time more accurately.
• Intraday updates now better prevent invalid activity times while still allowing non-time edits.

User management

• User management now supports SSO visibility for team members.
• Admins can manage user home addresses for proximity and scheduling workflows.
• Email change confirmation has a clearer, localized confirmation flow.
• Bulk user actions are more reliable, with clearer per-user errors for duplicates, mismatches, or invalid rows.
• Invite emails no longer include personal notes.
• Directory sync is more robust, including better handling for hidden or changed emails.

Notifications and polish

• Push notification troubleshooting is clearer, with improved device status, reconnect options, and diagnostics.
• The app now cleans up old service-worker registrations that could break push notifications or serve stale assets.
• Several modals, callouts, drawers, buttons, selects, spinners, and mobile and table views received polish and consistency improvements.
