Add date filter for email automation analytics (Open Rate & CTR)#2643

Currently, the analytics section for email automations only shows total Open Rate and CTR, without any time-based filtering.
It would be very helpful to allow users to filter results by date range (e.g., last 7 days, last 30 days, custom period).

This would help users identify trends, improve subject lines and email performance over time, get better results, and ultimately stay longer in the platform thanks to better insights.
