[feat](trx-frontend-http): adjust auth header and style ids

Keep the top bar visible while logged out, limit access to\nthe Main tab, and leave theme controls available while the\nrig selector stays disabled.\n\nRename the internal style ids from nord/arctic and\nmonokai/lime, including a compatibility remap for saved\nsettings.\n\nCo-authored-by: Codex <codex@openai.com>
