feat(event-form): auto-focus the title on a new event, optionally (#10)

Opening the new-event form now puts the cursor in the title field and raises the
keyboard, so the user can type the name straight away instead of tapping the
field first (issue #10). On by default — most events get a title — with a new
"Focus title on new event" switch in Settings → New event form to turn it off.

Only the create form auto-focuses: editing an existing event and opening a
prefilled/imported form never grab focus (guarded by !isEditing && title blank).

- SettingsPrefs: autofocusEventTitle (booleanPreferencesKey), default true.
- Plumbed through SettingsViewModel/UiState (settings switch) and
  EventEditViewModel/UiState (read by the form).
- EventEditScreen: a FocusRequester on the title InlineField, requested once per
  open from a LaunchedEffect when the guard holds.
- Strings (en + de), unit test for the new pref default/round-trip.

Bumps to 2.11.2.

+### Added
+- Jump straight to typing a title. When you start a new event, Calendula now puts
+  the cursor in the title field and opens the keyboard right away, so you can type
+  the name without an extra tap. It's on by default and only affects creating an
+  event — editing never grabs focus — and a new **Focus title on new event**
+  switch (Settings → New event form) turns it off. Thanks to @abrossimow for the
+  suggestion ([#10]).
