chore: complete rebranding from seanmorley15 to Alex-Wiesner/voyage

Replace all seanmorley15/Voyage repo URLs, ghcr.io/seanmorley15 container
image references, seanmorley.com/sponsor and buymeacoffee links with
the new repo (github.com/Alex-Wiesner/voyage) and new GHCR images
(ghcr.io/alex-wiesner/voyage-*). Attribution to original AdventureLog
author Sean Morley is preserved.
