Fix EZP-22124: inline image alignment is not respected

JIRA: https://jira.ez.no/browse/EZP-22124

# Description

The align parameter on the embed-inline content in the Online Editor has no effect in the frontend. This PR replaces #865 which seems to break some custom code (see comments). The idea in this one is to fix the templates to correctly handle the *right* and *left* alignment and to fix Online Editor to not propose *center* for the `embed-inline` view.

# TODO

* [x] fix the default templates
* [ ] fix Online Editor to not allow align center for *inline* elements
* [ ] fix the overrides in ezdemo, ezflow and ezwebin
