chore: upgrade to 0.3.1+v0.4.5001

Bump ghcr.io/bluesky-social/pds 0.4.219 -> 0.4.5001 (atproto/pds 0.2.19 -> 0.5.1).
Upstream renamed the service entrypoint from index.js to index.ts (ESM, type:
module, Node base image 20 -> 24), so update entrypoint.sh.tmpl to exec index.ts
and bump ENTRYPOINT_VERSION v1 -> v2 so the new swarm config is applied.
