As of #23867 this is now a real package, so updating the imports to
use the real package name, rather than relying on the alias. The
name change in the package name is because `I18n` is not a valid
name as NPM packages must be all lowercase.
This commit also introduces an eslint rule to prevent importing from
the old I18n path.
For themes/plugins, the old 'i18n' name remains functional.
Note that this commit will also disable daily grouping for datasets with more than 30 data points. This will also smartly do the grouping by month when grouping a full year.
1. It defaults to `cache: true` already
2. Setting it to `false` for non-GET request doesn't do anything
3. We were correcting `cache: false` GET requests to use `cache: true`
…so setting it to anything at all, for any type of request doesn't make sense (anymore)
Note that this is only applied on date-input and not the old date-picker for now.
This commit is also slightly modifying admin report dates form to ensure the native picker is correctly used, as a result: it doesn’t auto refresh on date change and fixes a border bug.
