The app was locked to portrait in app.config.js and the hand-kept
AndroidManifest.xml. Android 16 ignores that lock on screens 600 dp and
wider, so tablets and foldables rotated into layouts that were never
tested. This removes the lock in both places, keeps React state across
rotation and split-screen resizes (`smallestScreenSize` joins
`configChanges`), and fixes what broke in landscape:
- the thread pager sizes its pages from its own width and snaps back to
the open message after a rotation instead of showing half a neighbour
- compose and the thread view share one keyboard tracker; a rotation
with the keyboard open closes it, since Android sends no new keyboard
frame and the old portrait one blanked the whole landscape composer
- in a short window with the keyboard up the composer hides the format
bar and tightens its header so a few lines of text stay visible
- inputs with suggestions or context around them opt out of Android's
full-screen landscape keyboard
- month views fit whole rows to the real height, keep the month across a
remount, and the month dropdown re-measures and caps its height
- the week grid's header follows the remounted list after a rotation
- the event sheet's actions stay on screen in landscape
- every RN Modal allows all orientations, or iOS forces portrait
In the day, 3 days and week grids an event could only be started with a
long press, which few people find. Tapping an empty slot now marks it
with a "New event" block, and tapping that block opens the editor at
that hour; a second tap elsewhere moves the block. Long press still
opens the editor straight away. Tapping a day's header in the week or
3 days grid opens that day.
The editor also started events from a slot half an hour late, because
it rounded a time already on the hour up to the next half hour.
