Resolve lint issues due to new default rules

We could turn these rules off, but it seems that they indicate some important inconsistencies.

A few cases have been ignored inline because they should be investigated in more detail, which is out of scope for this PR:
- Metadata representation components compare `BrowseByDataType` to a `ResourceType`. Could be related to #2949.
- We assume that dynamic form dates are always represented by strings, but they can also be `Date` or `object` according to the library (see da1742ce05/projects/ng-dynamic-forms/core/src/lib/model/dynamic-date-control.model.ts (L5))
