test(calendar): pin the clock for the Paris today marker

The test of the today marker read the wall clock, so it only exercised
the Paris/local date mismatch between 22:00 and 24:00 UTC and passed
with or without the fix the rest of the day. Pin the clock to 22:16 UTC,
already the next day in Paris, so a UTC runner fails without the fix at
any time.

 [`.gitea/workflows/ci.yml`](.gitea/workflows/ci.yml) defines Gitea Actions validation, functional coverage, production builds, security scans, and Docker image publication. [Issue #268](https://gitea.nessar.fr/nessar/vac-optimizer/issues/268) tracks activation. Actions is enabled with owner approval; publisher credentials and live workflow validation are still pending. The [activation guide](docs/gitea-actions.md) records runner, credential, permission, and merge-gate requirements.
 
-The workflow runs on pushes to `develop` and `main`, `v*` tag pushes, PR opening/reopening/synchronization/edits, and manual dispatch. Other branches run CI only through their PR, so a branch without a PR gets no automatic CI or image. Manual runs validate without publishing images. Required jobs cover policy regression tests, GitFlow and Conventional Commits, ESLint, Prettier, `bun check` type checks, Bun coverage, the production build, Semgrep SAST, and Trivy dependency/secret scans. Coverage, build output, and SARIF reports are retained for seven days.

Coverage, build output, and SARIF reports are retained for seven days.
 
 Jobs that run project commands install Bun 1.4.3 with `scripts/install-bun.sh` (a checksum-verified download, no npm) and run their steps with a `PATH` that holds Bun but no Node. The job containers keep Node only for Gitea's checkout and artifact actions, which are JavaScript actions the runner executes itself; see the [activation guide](docs/gitea-actions.md#runners-and-permissions).
 
 Functional tests run with `bun test --isolate`; coverage is line-level only (Bun reports no branch or function data). The separate required benchmark job runs without coverage in a container limited to 3 GiB (JavaScriptCore has no heap-size flag, so this replaces the former 2 GiB Node heap cap) and keeps its 240-second hang guard, one warm-up and two measured repetitions of all seven scenarios. [#78](https://gitea.nessar.fr/nessar/vac-optimizer/issues/78) restored this gate after a complete local pass in 298.6 seconds; see [the measurements and hardware limits](docs/benchmark/issue-78.md). After [#302](docs/benchmark/issue-302.md) the local protocol takes about 41 seconds. Benchmark success is required for image publication and the aggregate `required` job. The lowered hang guard and tightened multipliers still need confirmation on the CI runners.
 
-The `required` job aggregates successful validation and expected image publication, accepting the image job's intentional skip for fork PRs and manual runs. Image jobs require successful validation and are limited to pushes to `develop`, `main` and release tags, and same-repository PRs. Registry credentials are confined to the publishing step.

 Both protected branches still require `gitlab-to-gitea/ci-conversion-required` until the owner approves the first merge message and a successful Gitea PR run, then replaces the migration gate with the actual pull-request context for `required`. Local validation does not satisfy this status. Historical CI reports and artifacts remain in administrator rollback backups; the original configuration is retained in Git history.

Preserve the previous slug normalization: lowercase the branch name, replace characters other than `a-z` and `0-9` with `-`, truncate to 63 bytes, and remove leading/trailing `-`. Choose branch names with distinct slugs. Only valid release tags can update `latest`. Automatic image publication and tag promotion begin after the owner provisions publisher credentials and validates publication permissions.
