Mark user-configurable classes as final (part 6/21)

Add the C++ `final` specifier to leaf, user-configurable component classes and
automation action/trigger/condition primitives so that classes meant to be
terminal cannot be subclassed by external components. Only classes never used as
a base anywhere in the tree are marked. Part 6 of 21, split alphabetically by
component (esp32_ble_client .. fujitsu_general).
