fix(fisher_summer_airconditioner): move work time to a disabled sensor

This is updated frequently, so having it as an attribute causes
the recorder data to grow excessively. Move to its own sensor and
disable by default so the user does not need to bother with it
unless they really want it.

Issue #6367
