Improved recurring tasks scheduling

Recurring task scheduling has been significantly extended, giving you more flexible and precise control over how and when tasks repeat.
With this update, you can now:
-> Schedule tasks with flexible frequencies:
Daily: with custom intervals
Weekly: choose specific weekdays and set custom intervals
Monthly: by exact day or patterns like "first Monday" or "last Friday"
Yearly: by month and day, or using advanced patterns similar to monthly scheduling
→ Preview deadlines before saving, a drawer shows upcoming occurrences based on your selected start date. 
→ View recurrence details directly in the task view, so you always know how often tasks are scheduled.
->See a new Frequency column in the recurring tasks list view, which shows only the interval (e.g. monthly, yearly), but when hovering over it reveals the full recurrence rule in a readable format.
→ See recurrence data now logged in the activity log.
Important change:
The Start Date has replaced the previous Deadline field, it now defines when recurrence begins.
