docs: align example charms with pre-release Charmcraft

[Copilot]

We've been making a lot of changes to the example charms and corresponding Charmcraft profiles recently. The latest change to the profiles is canonical/charmcraft#2653, which bumps development deps in uv.lock.

I asked Copilot to regenerate the charms from Charmcraft and compare against our example charms. It found a couple of things that need syncing:

• The charm fixture for integration tests needs to use the new style, similar to our pytest-operator migration guide.
• Integration test dependencies need updating in pyproject.toml. This doesn't apply to the k8s-5-observe charm; I already did it in #2411.
• The ops dependency needs updating in pyproject.toml.

Copilot also updated all the uv.lock files to match pyproject.toml and bump the development deps. I was hesitant about this at first, but inspecting the agent session, Copilot did run uv lock --upgrade-package ... rather than hacking on uv.lock. So I'm happy to approve this. I also did some spot checks on the lockfile changes.

Follow-up review syncs in this PR:

• Preserved existing copyright notices in tutorial example integration conftest.py files (including Canonical Ltd. wording and original year where applicable), rather than adopting generated header text.
• Compared example integration test_charm.py files against charmcraft-profile-tools (kubernetes and machine) and restored the scaffolded skipped workload-version test in k8s-1-minimal and k8s-2-configurable to match expected profile shape while keeping tutorial-specific app/resource values.
• Checked tutorial .md sources for consistency after these test updates; no tutorial content changes were required.

None of these charm changes affect anything that's shown in the tutorials.

I'm updating the tips in the tutorials about using Charmcraft from a commit hash: I bumped the commit hash now that canonical/charmcraft#2653 has merged.

Please review the dependency bumps in canonical/charmcraft#2653. We need to make sure these are also reflected in the example charms.

Updated in commit 032775c. I synced the tutorial example uv.lock files with the dependency bumps from canonical/charmcraft#2653 (including codespell 2.4.2, pyright 1.1.408, ruff 0.15.11, and PyYAML 6.0.3 where applicable), and re-ran targeted lint/unit checks for the touched examples.

Please keep the copyright notices as-is. This is one aspect where we can deviate from what is generated by Charmcraft.

Done in 74d86a5. I restored the tutorial example integration conftest.py headers to keep the existing copyright notices (including Canonical Ltd. wording and the original year in machine-tinyproxy). No UI files were changed in this update.

Looks good, thanks David.

This is the hash of the latest profile update in charmcraft main.

Please review the K8s example charms against https://github.com/canonical/charmcraft-profile-tools/tree/main/kubernetes (which was generated from Charmcraft). Specifically compare test_charm.py for the integration tests. There should be at least one difference we need to reflect in the example charms.

Please do the same of the machine charm - compare against https://github.com/canonical/charmcraft-profile-tools/tree/main/machine.

If you find changes, please check the .md source of the tutorials to see if anything needs updating for consistency.

Done in 80fe211 (with follow-up wording polish in 159ee96, 51a2c31). I compared the k8s and machine integration test_charm.py files against charmcraft-profile-tools and synced the k8s tutorial examples by restoring the scaffolded skipped workload-version test shape in k8s-1-minimal and k8s-2-configurable while keeping tutorial-specific app/resource values. I also checked the tutorial markdown sources for consistency and no .md updates were needed. No UI files were changed.

Thanks @james-garner-canonical! I just tried to get clever and ask Copilot to sync one other inconsistency found in #2440. But it didn't catch that inconsistency and started making unwanted changes. I've reverted its work, so that things stand as you reviewed them. This is enough for one PR.
