Allow users to make a message recurring (daily, monthly, yearly, etc.)

[ibsule]

Summary

Enable support for recurring messages so that users can schedule messages to repeat at specific intervals—such as daily, monthly, or yearly.

Details

• Add UI and API support for scheduling messages as recurring
• Support common repeat intervals (daily, weekly, monthly, yearly)
• User should be able to set:
  • Start date
  • Recurrence pattern (e.g., every X days/weeks/months/years)
  • Optionally: an end date or number of occurrences
• Consider how to display/edit/cancel individual instances vs. the full series
• Consider notification handling for recurring messages
• Ensure proper backend logic to generate/persist next occurrences

Motivation

Recurring messages improve the usefulness and automation potential of the app (e.g., reminders, celebrations, periodic tasks).
