Summary

Fix analytics queries to correctly handle created_at_epoch stored in milliseconds
startDate calculation now uses milliseconds: Date.now() - (daysBack * 24 * 60 * 60 * 1000)
date() function for daily grouping now divides epoch by 1000: date(created_at_epoch / 1000, 'unixepoch', 'localtime')

Problem

The "Memories Over Time" chart was only showing January 1st because the epoch timestamps were being treated as seconds instead of milliseconds.

Test Plan

Verify dashboard analytics endpoints return correct date ranges
Verify "Memories Over Time" chart shows actual dates

The created_at_epoch column stores timestamps in milliseconds, but
the analytics queries were treating them as seconds:

1. Changed token_count → discovery_tokens (column was renamed)
2. Fixed startDate calculation to use milliseconds
3. Fixed date() function to divide by 1000 for proper date grouping

This fixes the "Memories Over Time" chart showing only Jan 1st.
