templates: jmap, dav, karakeep, ttrss for personal-service projects

jmap and ttrss are custom images (mysources.co.uk/michal/{jmap-mcp,ttrss-mcp});
dav-mcp and @karakeep/mcp run on the node runner. Health checks are real
backend calls. Applied live 2026-09-30; these seeds keep the next mcpd
image rebuild from reverting them.
