Fix nine GUI bugs found during local-workspace smoke test

- crates/onyx-core/src/webdav.rs: rename `getpassword`/`setpassword`
  (7 call sites) to `get_password`/`set_password` so `cargo build`
  and the CLI compile again under the default `keyring-storage` feature.
- ConfirmDialog.svelte: intercept Escape at window capture phase and
  expose a module-level open-count so TasksScreen's Escape handler can
  defer; previously Escape on a dialog both dismissed the dialog AND
  popped the task-detail view behind it. Cancel is also focused on
  mount for keyboard users.
- TasksScreen.svelte: extend the taskStack cleanup effect to collapse
  back to parent detail when only the subtask is gone (was leaving a
  blank third panel); focus the new-list input when it appears; reset
  the Completed section's expand state when switching lists.
- TaskDetailView.svelte: re-sync local title/description state when
  the task prop's content changes (unless the user is editing), so a
  sync pull doesn't get silently overwritten on next save. Bail out of
  the parent delete if a subtask delete fails instead of orphaning.
- app.svelte.ts: deleteTask now returns a success boolean; move the
  "No Date" group to the end of the grouped-by-date view so Overdue
  and Today surface first.
- SetupScreen.svelte: strip trailing separators before splitting the
  picked folder path so "…/MyTasks/" yields "MyTasks" instead of the
  literal fallback "workspace".

Verified live under Xvfb for the three user-visible cases (ConfirmDialog
Escape, orphan subtask collapse, new-list autofocus). Screenshots in
screenshots/smoke-test/. cargo test --lib -p onyx-core is green
(162/162); npm run build succeeds.
