v2.0.2 — English tag aliases, English-only website, undo-body flaky fix

- tags: accept #birthday and #appointment as English synonyms for
  #geburtstag and #termin. Normalised to the German canonical form at
  extractTags() write-time so every downstream check (parseTags /
  calendar logic / board filters) keeps working without per-call-site
  aliasing. Editor body-regex extended so the "new appointment"
  heuristic and auto-sync trigger on either variant.
- website: replace #termin/#geburtstag with #appointment/#birthday in
  tag chips, calendar feature list, and calendar legend.
- tests: fix flaky "Undo: Editor Save → Ctrl+Z reverts body change"
  that raced doSave(). The test polled the server for the patched body
  and fired Ctrl+Z as soon as it landed, but the undo shortcut is
  guarded by !guards.isOpen('modal'), and closeModal() only runs after
  the post-patch _reloadAll — on fast servers the key was swallowed.
  Poll now also waits for the modal `.open` class to drop.
