The Verfahrensablauf and "Was kommt nach" tabs now render results
immediately, without requiring a click on "Fristen berechnen". The
button stays as a manual force-recalc affordance.
- Pre-select the first proceeding type on load so step 3 has data
out of the box.
- Pre-select the first trigger event on first event-tab activation
(or right after the list loads if the tab was already active).
- Auto-recalc on date / proceeding-type / condition-flag change.
- Debounce input events to 200ms so spam-edits coalesce into one
request, with a per-mode sequence counter so a stale fetch result
can never overwrite a fresher one.
