docs: migrate Release/Download targets to Gitea; keep stars/forks on GitHub

GitHub mirror is no longer maintained; v1.3.4+ releases land on Gitea only.
Repoint the Release-version badge and Download-Latest button (href + shields
endpoint + logo) at git.simpleremoter.com so visitors don't end up on a stale
GitHub release page.

Stars/forks badges stay on GitHub — vanity counters reflecting historical
accumulation, not navigation targets.

Also: server/go/README.md yama-issue-token link and the line-294 Markdown
"Releases" link in all three READMEs now point at Gitea.
