Fix PlayOptions YAML round trips

[Old-Ding]

Summary

• decode the existing actions_to_filter and exclude_actions YAML keys
• decode the existing loop and topic_remapping_options YAML keys
• encode negative rclcpp::Duration values with the standard ROS sec/nanosec representation
• add text YAML round-trip coverage for every field emitted by the PlayOptions encoder and the default negative acknowledgement timeout

Testing

• verified the Rolling baseline has 27 encoded keys but only 23 matching decoded keys
• verified the updated converter has identical 27-key encode/decode sets
• verified the regression test assigns and checks a non-default value for all 27 encoded fields
• verified the default wait_acked_timeout = -1ns encodes as sec: -1, nsec: 999999999 and round-trips
• ament_copyright on the new test
• UTF-8 without BOM and CRLF checks
• added-line 100-column check
• git diff --check

The repository-native C++ tests were not run locally because this Windows environment does not have the ROS 2 build dependencies or colcon. Repository CI covers the new round-trip tests.
