docs(changelog): cut 2.16.0

Consolidate the release under a single 2.16.0 heading dated today and fold
in the work that had accumulated in Unreleased. Add the entries the log had
been missing as PRs merged: app-name toggle (#44), the Arabic/French/Italian
translations, the custom recurrence picker redesign + end-date fix (#42),
multi-day agenda events (#83), and dark-theme picker bar icons (#70).
Regenerate the fastlane per-version changelog.

-- The "Upcoming" agenda widget now scales its text and rows to the size you give
