The firmware page accepted any valid image, also one built for a
different board whose SFP, LED and button pins differ. Every image
carries its machine name as a NUL-terminated string, the same one the
switch reports as hw_ver; when the selected image lacks it, the page
now warns below the check result and in the confirmation dialog. The
upload stays possible on purpose.

Adds a German dictionary to LANG in app.js (all 317 keys, placeholders
unchanged), the language selector entry in index.html and the login
strings in login.html. Uses Swiss spelling (ss instead of ß), which
reads correctly for all German speakers.
Checked against a mock of the httpd endpoints: every section renders
with the German strings; no layout changes compared to English.
