2.18.0

Cut 2.18.0. Adds the retroactive entries for #114 and #70, whose PRs
landed on main directly rather than on this branch.

The fastlane changelog is now hand-written and capped at 500 chars —
Play rejects longer "What's New" text and F-Droid truncates it, while
copying the CHANGELOG.md section produced up to 8k chars. The sync
script keeps a committed file and only falls back to CHANGELOG.md when
one is missing.

+### Fixed
+- The back gesture closes the sidebar instead of the app. With the drawer open,
+  swiping back left Calendula altogether rather than putting the sidebar away
+  ([#114]).
+- The sidebar lines up. "Calendula", "View" and "Calendars" now share the left
+  edge of the rows under them, and the view, jump-to-date, Settings and calendar
+  rows sit on one vertical axis instead of each icon finding its own — the same
+  alignment the Settings screens use ([#114]).
+- The status- and navigation-bar icons follow Calendula's own light/dark choice.
+  Setting the app dark while the system stayed light — or the other way round —
+  left the clock and battery drawn for the system's theme, so they could sit
+  near-invisible against the app's own bar ([#70]).
