v2026.7.5 — Filtered departures no longer starved at busy stops

Improvements

• Line/destination filters at busy stops (#43): when a line or destination filter is active, the integration now fetches a larger departure board from the API before filtering, so you actually get up to your configured "Number of Departures" of matching results — instead of 1–2 because unfiltered lines used up the board first. No config change needed; behaviour is unchanged when no filter is set.
