Note

Low Risk
Low risk: adds a new analytics pixel and a single call site when canRunPir() becomes true, with minimal impact on PIR behavior beyond an extra enqueue.

Overview
Adds a new Android PIR daily analytics pixel, m_dbp_user-eligible_d, to report when a user is eligible to run PIR.

Wires the pixel through PirPixel/PirPixelSender and emits it from PirDataUpdateObserver when canRunPir() transitions to enabled; updates unit tests to inject and mock the new PirPixelSender dependency.

Bugbot Autofix prepared a fix for the issue found in the latest run.

• ✅ Fixed: JSON5 pixel key includes redundant _d suffix
  • Changed pixel key from 'm_dbp_user-eligible_d' to 'm_dbp_user-eligible' to match the convention where the daily_count_short suffix appends '_d', preventing the double '_d_d' pattern.
