Adds a discreet "Quellen & Lizenzen" link to the SDK sidebar footer (below the existing Export button) pointing to the /sdk/licenses page shipped in commitdfac940. Part of Task #24 (AGB/Impressum audit) — the legal mandate that attribution be discoverable for every output is now satisfied at three layers: - platform-wide overview reachable from every SDK page (this commit) - per-export footer in compliance PDFs (commit07cc00d) - inline source badge per control via <SourceBadge> (commitdfac940)
