TAN-8563: Early access opt in

[EdwinKato]

Changelog

Added

• Admins can now switch on selected features that are built but not yet released, from Profile settings > Early access. What an admin switches on only changes what that admin sees — every other user on the platform, including other admins, is unaffected. The list is curated by us: only features we have explicitly opened for early access appear there, so this can never be used to turn on a feature the platform is not commercially entitled to. The first feature offered is the redesigned project back office (parallel participation).

Technical

• A feature opts into this by adding "early_access": true to its entry in the settings JSON schema (or overriding early_access? in an engine's feature specification). That list is the allowlist, enforced both on write (model validation) and on read.
• Opt-ins are stored on users.early_access_features. ApplicationController narrows them to (admin) ∩ (registry) into Current.early_access_features, which AppConfiguration#feature_activated? and #public_settings consult — so useFeatureFlag, useFeatureFlags, FeatureFlag and GetFeatureFlag needed no changes, and flag-gated API endpoints work too. Current is empty outside a web request, so jobs and rake tasks are never affected.
• An early access feature must be a bare on/off flag: the override lifts allowed/enabled but cannot satisfy dependencies or supply a required-settings value. A spec enforces this.
• Serving a different app configuration per admin is safe because the aggressive caching engine already excludes non-residents from the action cache.
• Removing a feature from the registry makes stored opt-ins inert with no data migration.

For translators

New strings in front/app/containers/UsersEditPage/EarlyAccess/messages.ts, all in the new Early access section of the profile settings page (/profile/edit), visible to admins only:

• app.containers.UsersEditPage.EarlyAccess.earlyAccessTitle (Early access) — section heading.
• app.containers.UsersEditPage.EarlyAccess.earlyAccessSubtitle (Try out features we are still finishing. What you switch on here only changes what you see, not what anyone else on the platform sees.) — section subtitle.
• app.containers.UsersEditPage.EarlyAccess.parallelParticipationTitle (Redesigned project back office) — label next to the toggle.
• app.containers.UsersEditPage.EarlyAccess.parallelParticipationDescription (The reworked project setup and project page, where participation methods can run side by side instead of one after the other.) — helper text under that label.
