Date-Based Filtering for Memories

Description
Currently, the app only allows searching conversations by keywords. Users would benefit from an enhanced filtering option that allows them to browse conversations based on a specific date using a calendar UI.

Proposed Feature

• Add a calendar icon in the UI.

• Tapping the icon opens a date picker/calendar view.

• Users can select a date to filter conversations from that specific day.

• Once a date is selected, only conversations from that date will be displayed.

• Users can reset the filter to return to the full conversation list.

User Flow

• Tap on the calendar icon next to the search bar.

• A date picker or full calendar view appears.

• Select a date → The conversation list updates to show only that day’s logs.

• To reset, tap a "Clear Filter" button or reselect the calendar icon.

Benefits
✅ Faster navigation through historical conversations.
✅ Intuitive UI for users who want to retrieve past conversations.
✅ Complements the existing search functionality for better organization.
