* Rebrand MMTL to MeBox across codebase and assets Rename the project display name, Go module path, environment variable prefix (MEBOX_*), Docker image references, and UI branding from MMTL/mmtl to MeBox/mebox. Replace logo assets with the new MeBox icon and keep legacy SQLite migration support for existing mmtl.db deployments. Co-authored-by: truewhile <truewhile@users.noreply.github.com> * Fix logo icons: use cube-only crop without truncated text Previous icon generation cropped too much of the source image, including partial MeBox wordmark text that was cut off in square icon containers. Regenerate logo-64/192/512, favicon, and SVG from cube-only region.
