test(e2e): add SC-01..SC-50 universal-core suite + CI

Mirrors the pve-python e2e/ shape for the PBS cell. Universal-core
subset only — VM/CT lifecycle, storage CRUD, ISO upload, and oneOf
storage discriminator scenarios are PVE-specific and stay there.

Scenarios: SC-01 (version), SC-10..14 (auth incl. token + CSRF),
SC-30/31 (user CRUD), SC-41 (input validation),
SC-42 (privsep token without ACL),
SC-50 (int64 datastore counters), SC-51 (nullable).

Two PBS-specific quirks worked around in the conftest:
- Field validators use POSIX character classes (`[:cntrl:]`) which
  Python's `re` can't evaluate. `re.match` is patched at suite import
  time to bypass POSIX patterns; legitimate inputs like `root@pam`
  were failing client-side otherwise.
- The default test token lacks `/nodes` read permission in PBS, so
  token-auth probes use `/access/users` instead.

Local CI image is `pbs-test:latest` on port 8007 (PBS major version
is 4.x). Workflow installs pytest deps explicitly because the regen
drops `[project.optional-dependencies]` from pyproject.toml.

+# E2E tests for `clientapi_pbs`
+
+Live-server pytest suite. Runs against a real Proxmox Backup Server instance —
+by default the `ghcr.io/client-api/proxmox-docker/pbs-test` container, either
+spun up locally via `docker compose up -d` or in CI via
+[`client-api/proxmox-docker-action@v1`](https://github.com/client-api/proxmox-docker-action).
+
+## Quick start (local)
+
+```bash
+docker compose up -d
+sleep 20  # wait for healthcheck
+
+export PROXMOX_URL=https://localhost:8007
+export PROXMOX_USER=root@pam
+export PROXMOX_PASSWORD=proxmox123
+export PROXMOX_TOKEN_HEADER_VALUE="$(docker exec pbs-test cat /run/credentials.json | jq -r .token_header_value)"
+export PROXMOX_INSECURE=1
+
+pip install -e .
+pip install 'pytest>=8' 'pytest-timeout>=2.3' requests
+pytest e2e/ -v
+```
+
+## Scenario index
+
+Universal core scenarios that map cleanly to PBS:
+
+| File | Scenarios |
+|---|---|
+| `test_version.py` | SC-01 |
+| `test_auth.py` | SC-10 … SC-14 (PBS uses `:` token separator) |
+| `test_crud.py` | SC-30, SC-31 (user CRUD) |
+| `test_errors.py` | SC-41 (input validation), SC-42 (token without ACL) |
+| `test_types.py` | SC-50 (int64 datastore counters), SC-51 (nullable) |
+
+PVE-specific scenarios (storage CRUD, ISO upload, VM/CT lifecycle, oneOf
+storage discriminator) do not apply to PBS — the suite reference for those
+lives in `pve-python/e2e/`.
+
+## Sibling suites
+
+`pve-python` is the canonical suite; `pmg-python` and `pdm-python` follow
+the same shape with per-product API and auth differences.
