fix(web): restore running-log 300px height and close streams on card removal

CSS cascade fix: .task-log-tail.running-log combinator overrides
.task-log-tail's 90px max-height for RUNNING/BLOCKED cards, restoring
the intended 300px prominent log panel. Closes EventSource streams in
taskLogStreams when cards are removed from the board.
