Fix GrampsWeb subpath: patch API/lang/font paths in JS at startup (STI-90)

GrampsWeb's frontend JS hardcodes absolute paths like "/api/...",
"/lang/...", "/fonts/..." which bypass <base href>. These now get
rewritten to "/ahnenforschung/api/..." etc. at container startup,
matching both double-quoted and template-literal (backtick) patterns.
