Pull request overview

This PR aims to ensure EdgeTech position-only updates are not skipped/rejected due to duplicate (device_id, recorded_at) collisions by switching update recorded_at generation to use the current time, and adjusting tests accordingly.

Changes:

• Update _create_gear_payload to use datetime.now(timezone.utc) for update recorded_at (when include_initial_deployment=False).
• Remove the recorded_at de-dup/skip logic in _identify_buoys, based on the assumption that update recorded_at values will now be unique.
• Update/rename tests to validate the new recorded_at behavior for updates.
