fix(telega): build the server image locally to meet tdlib 1.8.66

MELPA's 2026-08-18 telega raised telega-tdlib-min-version to 1.8.66. The pinned upstream image ships 1.8.64, so telega killed its own server on every launch. Upstream's only 1.8.66 image won't start: it's missing libglycin (zevlg/telega.el#596).

docker/telega-server/Dockerfile derives from that upstream image, pinned by digest, and adds the one missing package. make telega-image builds it as cj/telega-server:1.8.66-glycin, cj/telega-docker-image defaults to that tag, and a test holds the two equal. cj/telega now refuses to launch with a make telega-image hint when the image isn't built, since docker would otherwise try to pull a local-only tag from the registry. setup-telega.sh points at the make target instead of M-x telega-server-build.

I chose the local build over pinning the telega package back to 20260706.2147. The derived image satisfies both machines' floors. package.el can't pin a version and MELPA serves only its latest build, so nothing would enforce the package pin. When #596 is fixed upstream the pin returns to a registry digest and the Dockerfile goes.
