Update urlaubsverwaltung/urlaubsverwaltung Docker tag to v6.12.1

Work on this repo happens in a Coder workspace that has no 1Password CLI.
The rule that tea may only be called as 'op plugin run -- tea' therefore
described an environment that no longer exists here, and following it meant
either waiting for a tool that is not coming or ending with a pushed branch
and no PR.

tea is now called directly. It carries the workspace's stored login, so what
it opens is authored by the bot account - accepted, and named in the report
when it happens. The older instruction is kept for machines that do have op.

Signing needed the same correction: it runs through the workspace's own SSH
signer, not op-ssh-sign, and the check is 'git log --format=%G?' printing G.

 Additional rules for all commits, PRs, issues, and comments:
 
 - Do **not** add a `Co-Authored-By` trailer and do **not** append "Generated with Claude Code" footers.
-- **Commits must be signed.** Verify the signature before opening the PR; if `op-ssh-sign` fails, stop and report rather than pushing unsigned work.
+- **Commits must be signed**, and in the Coder workspace they are: signing runs through its own SSH signer (`gpg.format = ssh`, `gpg.ssh.program = coder-git-ssh-sign`, `commit.gpgsign = true`), so no 1Password step is involved. Verify before opening the PR — `git log --format='%G?' -1` must print `G` — and if signing fails, stop and report rather than pushing unsigned work, because branch protection rejects it at merge time.

 Everything runs on the Gitea instance JLab-Git: issues, pull requests, CI and Renovate. github.com is a push mirror with Actions and Renovate **switched off**, and it lags until the mirror runs. README, "Where this repo lives", holds the measured differences between a Gitea runner and a GitHub one.
 
-- **`tea`, not `gh`** — and only as `op plugin run -- tea`. A bare invocation falls back to the wrong identity. Every call costs a 1Password confirmation, so bundle them and never poll.
+- **`tea`, not `gh`.** Work happens in a **Coder workspace, and it has no `op`** — that is the normal case here, not a broken environment, so do not wait for the 1Password CLI or propose installing it. Call `tea` directly; it carries the workspace's stored login and opens PRs and issues under the **bot account**, which is accepted. Say so in the report when something is authored that way. (`op plugin run -- tea`, the older instruction, applies only where `op` actually exists.)
 - **Remotes are named `github` and `JLab-Git`** — there is no `origin`. `JLab-Git/main` is the leading copy; say which remote you mean, because `git push` without one is ambiguous here.
 - **Branch protection with a signature requirement is active**, and signatures verify on Gitea. A commit that is not signed does not reach `main` — check before opening a PR, do not discover it at merge time.
 - **No merge queue.** Gitea has none, and its place is taken by **auto-merge on green checks**: the PR is armed once and merges itself when the required checks pass. Rule 6 above is unchanged — the user merges, and an agent never merges its own PR or arms auto-merge on it.
