feat(admin): draft a pdfformat page and 'create cards feature'

Description

Some new features developed while setting up "Fresque Oceane".

• A new pdfformat page to manipulate pdfformats
• New feature create card

PdfFormat edition

Route: <i18n>/pdfformat/<pdfFormatFilename> (ex /fr-FR/pdfformat/pdfformat-v6.0.json)

We can:

• load (locally) a pdf and see its content
• for each entry in pdfformat, edit pdfpage, cardid and cardside
• create new entries, each new entry is initialized with pdfpage = pdfpage of previous entry + 1 ; cardside = opposite side of previous entry ; cardid = previous cardid
• see in real time the pdf page of the current entry (see screenshot bellow)

We can’t

• delete entries ^^
• list all pdfformats
• publish results (should be fixed), for now copy-paste gitlab request from network panel.
