Fix four bugs and add logo/branding polish

- docker-compose: add register-user service (profiles: [tools]) with YAML anchor to avoid env duplication
- src/index.ts: show localhost instead of 0.0.0.0 in startup message
- file-view: render <img> inline for image/* MIME types
- file-list: add Copy link button per row (requires baseUrl param)
- layout: add hideLogo option; file view page hides the logo
- style.css: remove uppercase from .logo (Nanodrop not NANODROP), add button.copy-link styles, add .file-view img styles, widen last td
