Various fixes

[NicoPennec]

Problem

• On the timesheets tab, clearing the selected date raises an error on loading data.
• On the Task Type page, the Estimation tab fails to load.
• The newsfeed page may display news inconsistently (missing news or unwanted production news)
• Can't edit past timesheets at all anymore #1622
• Sentry no longer runs on Kitsu 0.20

Solution

• Disable the clear date button to avoid sending an invalid date to the API.
• Fix estimation display (wrong caching of entity maps).
• Fix news loading (Improve init data and load more data).
• Fix available dates on timesheets (parameters reverted).
• Enable Sentry (fix the SDK configuration for Vue 3).
