This PR updates the German translations (de and de_CH).

New strings

• Compact mode of the Assets fieldtype ("Pick new one", "Select Asset")
• "Search results"
• markdown.config.buttons
• video_fieldtype_cloudflare_manifest
• link_cannot_reference_itself

Consistency fixes

• Use "Handle" consistently instead of "Bezeichnung"
• Keep "Theme" untranslated instead of "Thema"
• Use "neu anordnen" for reordering instead of "sortieren"
• Use "Antworten" for form submissions in permissions
• Add the missing :count placeholder to the "Assign groups/roles" confirmations
• Reword the integer fieldtype instructions, the "Clear" labels and "Not listable"
• Fix typos ("BCC", ß/ss in de_CH)

Drafted with the help of Claude and reviewed by hand.
