Feedback from #141: when resizing with the left hand, the finger covers both the event's own time and the hour-column badge. While a selected event is moved or resized, the time under its title in the top bar now follows the gesture. It shows what letting go would save, using the same calculation as the drop (real duration for a move, the untouched edge kept for a resize, DST-safe), and stays on the saved times until the event leaves its starting slot. It only recalculates when the snapped slot changes. Closes #141 Co-authored-by: Jean-Luc Makiola <business@jeanlucmakiola.de> Reviewed-on: https://codeberg.org/jlmakiola/calendula/pulls/403
