Various fixes

[NicoPennec]

Problem

• In a task, when you edit a value in the comment form in fullscreen and then exit fullscreen mode, the edit is not applied to the comment form in the side panel.
• Users with a timezone configured in their Profile that is different from the computer's timezone have date shifts in schedules.
  Sound assets (e.g., mp3 files) are not played in the playlist player (see MP3 files in playlist bug and improvements #1517).
• Some outdated npm dependencies.

Solution
-Sync comment forms in the task side panel and the task page (using provide/inject to share the v-model)

• Fix timezone support in schedules.
• Fix playback of sound assets
• Bump npm dependencies.
