WIP: Add notification preferences and improve filtering

[rabble]

Summary

• Added notification preference settings to control who can send notifications (Anyone, People I Follow, My Network)
• Added clarifying text 'Including people outside your network' for the 'Anyone' option
• Fixed notification filtering to respect user preferences
• Added thread replies toggle for notifications
• Improved debugging for notification filtering issues
• Fixed localization format specifiers

Test plan

• Check that notification settings show the new preferences
• Verify that notification filtering works correctly based on selected preference
• Test that the 'Anyone' preference is the default
• Ensure notifications are only received based on selected preference
