Pull request overview

Adds per-camera telemetry for how often AprilTags are detected, and resets the stat at the start of each enabled period so the value reflects the current run.

Changes:

• Track total frames vs. frames-with-targets in Cameras and compute a running detection percentage.
• Publish each camera’s detection percentage to SmartDashboard.
• Reset stats on autonomousInit() and teleopInit() via DriveSubsystem → PhotonVisionOdometry.
