Add recur field to task creation panel

[Hell1213]

Add recur field to task creation panel , allowing users to set when a task begins.

Description

Added a recur dropdown to the task creation dialog with options: daily, weekly, monthly, yearly. Users can now create recurring tasks. Backend validates that a due date is set before allowing recurrence (Taskwarrior requirement).

• Contributes to: Add more Fields to the Add Task Panel #188

Changes Made

• Updated backend to handle recur field
• Added validation: recur only works when due date is set
• Updated all types and tests

Checklist

• Ran gofmt -w . (for Go backend)

Done with review I have added recur dropdown to task creation dialog with daily/weekly/monthly/yearly options. Backend validates that due date is set before allowing recurrence (Taskwarrior requirement).
