Combine phases into single treatment record
Currently each individual phase (whether an entire Acute/single-phase treatment or each phase of a Chronic/multi-phase treatment) is treated as its own treatment record. For a given horse, the total number of treatments is often drastically over reported (by a factor of two for ones being treated for chronic conditions). Though the parameters change from Phase 1 to Phase 2, the dose for a given treatment should be summed between Phases to give one single value for one single treatment. The "end-point" of what is considered a treatment and any partial treatments should be handled as they currently are: i.e. when the timer on the "last" phase of a protocol runs up (for single-phase protocols this is the only phase) and/or when the user changes the protocol or exits the treatment screen.
