GaltRanch c94d9e265e fix(umbrel): pin container UID to 1000 to fix Umbrel permission errors
Umbrel forces `user: "1000:1000"` in docker-compose, but the previous
Dockerfile let useradd assign the next-free UID. Since ubuntu:24.04 ships
a pre-existing `ubuntu` user at 1000, `pyblock` ended up as 1001, causing
permission errors on the bind-mounted config dir reported in
getumbrel/umbrel-apps#5258.

- dockerfile: remove the default `ubuntu` user and pin pyblock to UID/GID
  1000 so file ownership matches the user Umbrel runs as.
- entrypoint.sh: fail fast with a clear, actionable message when the
  config dir is not writable (covers future UID-mismatch regressions).
- umbrel/: bump image tag and app version to v4.0.1 with release notes.

Verified with `docker run --user 1000:1000` and an empty bind-mount:
all 5 config files generated successfully, ttyd serves on :6969.
