[KleinanzeigenBridge] random improvements and fixes

Previous MR #4820 introduced a bug where the URI wasn't getting
expanded. This is because it is obtained from a non-standard data-uri
attribute which defaultLinkTo() doesn't support.

On top of that:
- sanitizes the HTML in Content
- use a longer Description found in JSON
- fix timestamp processing, including for relative Today and Yesterday strings
- move media to enclousures
- be explicit about elements chosen to augument the description
- simplify the image URL processing
