Marc-André Bombeck 91571d4674 fix(medications): count the whole cadence in the supply runway
The runway estimate read FREQ=MONTHLY as one dose every 30 days whatever
its INTERVAL, so a quarterly injection with two doses left showed about 60
days of supply instead of 180. FREQ=DAILY;INTERVAL=2 counted as daily, a
yearly rule ignored INTERVAL and BYMONTH, and a monthly rule ignored extra
BYMONTHDAY values. A CYCLIC schedule was counted as if it never paused,
and a PRN schedule as if it were due every day. The rate now honours
INTERVAL for every frequency, counts the listed days and months, scales a
cyclic schedule by on / (on + off) and leaves PRN out. The low-stock job
selects the schedule type and cycle lengths so it reads the same rate.

Whole-dose counts no longer lose one to binary floating point: 2.4 mL at
0.8 mL per dose is 2.9999999999999996 in IEEE 754 and used to read as two
doses. The stock summary, both runway estimators, the list and detail
routes, the GLP-1 route, the Coach snapshot and the inventory readout now
floor through one helper that treats anything within 1e-9 of the next whole
number as that number.
