test: the platform test covers what the CLI manages, not only runs

[achoimet]

The platform test now goes through the acceptance criteria of card 14235 on dev, not only a pipeline's experiment runs. 81 checks in all, up from 15.

With the team token (CLI-E2E): run an experiment from a template with a placeholder, set and add run properties, list a run's artifacts, and a schedule's whole life (create, get, diff, update, apply, enable, disable, delete). Also services: apply, diff, the profile's template offered, link and unlink an experiment, risk, variables, delete. Plus target stats and the action list.

With the admin token (STEADYBIT_E2E_ADMIN_TOKEN): templates (apply, diff, placeholders), the run property's definition and association, service profiles, environments and their variables, and teams: apply, diff, environments, and members, which uses an unknown address and never a real person. Also access tokens (create, use, recreate, the old one stops working, delete), a hub (apply with sync, diff, resync, delete), webhook, preflight and preflight-action integrations (apply, diff, delete), and reads of the audit log, kill switch, reports and license. Without the secret these checks are skipped.

Safety on a shared platform:

• Everything an admin creates is named cli-e2e-ci-*, and the cleanup deletes what matches by kind, including what a crashed run left.
• Integrations are scoped to a team of the test's own, CLIX, which runs nothing, so no webhook is ever called.
• The service and environment queries match no target.
• The schedule starts in 2099 and is enabled only for a moment.
• Nothing is imported from the hub.
• The kill switch is only read, and no invitation is sent.
• Tokens only go through the environment, never a command line, so a failing check, which shows its command, cannot show one. Tokens the test creates are masked in the job log and expire the next day at the latest.

A bug it found: execution property set with one --value sent a scalar, which the platform refuses for a list property ("must be a list of strings"). The CLI now reads the property's definition and sends a list for *_LIST types. When it cannot read the definition, it sends the value as given, as before. There is a changelog entry under v6.2.2.

Two things found, not changed here: right after apply, diff reports drift for an environment (the platform returns query beside predicate.query) and a service (a validation parameter the platform defaults). The test diffs what get wrote, which is what a repository keeps.

I ran it locally against dev with an admin token in place of both. All checks passed, and afterwards dev had no cli-e2e template, service, profile, environment, hub, token or integration left, and no CLIX team. This PR changes e2e/platform.sh, so it runs here with the real team token, which may show checks that need admin.
