* Remove hardcoded strings

From https://github.com/UPC/ravada/issues/1546

    Some of the text strings in the frontend templates are hardcoded
    instead of being inside "l" code so they can be translated.

* Define newly added entries in English file

From https://github.com/UPC/ravada/pull/1602#issuecomment-937707661:

    Remember this,
    https://ravada.readthedocs.io/en/latest/devel-docs/translations.html#new-entries.
    All new english entries must be defined in the english file, en.po
    in order to be later translated from Weblate.

    May you to add new entries in en.po? Thanks in advance.

* Remove hardcoded strings, add to localisation file

fix(backend): Refresh after spinoff

From UPC#1567

    When a clone is spinned off, the XML contents of the source file are outdated.

After spinoff we refresh volume info, that should update XML definition.

While we find where to put the docker image and autobuilds, we let it do a docker build every time.
