Owner asked for total minutes, call time and missed calls in one place, and the money left on
voip.ms. Reports now totals answered calls, talk time and outside minutes (in from arrival, out
from the answer: roughly what the provider bills), charts outside minutes per day, and shows each
voip.ms trunk's balance (getBalance; verify with a real account).
GET /api/reports/summary and /api/reports/queues (company-time-zone days, last 30 by
default, a year at most) and the Reports page: totals, stacked bars per day, missed per
day, a weekday x hour heatmap and the queue table. Plain divs, no chart library.
