Various fixes

[NicoPennec]

Problem

• On Breakdown page with all episodes selected in top bar, when importing CSV file, the episode field is required but shouldn't be.
• On studio Settings page, some fields can be empty.
• In Schedule, a long member name can be truncated in the UI.
• An instance without production raises errors in web console.

Solution

• Fix required columns on import CSV in Breakdown.
• Set some fields as required in Settings.
• Add ellipsis on long member names in Schedule.
• Fix silent error on if no production

In addition, bump npm dependencies.
