Subject: [PATCH] Add release channel selector components, subject
 autocomplete, and related tests

- Implement components for `ReleaseChannelSelector`, including panel and sidebar variants.
- Add `ReleaseAssignmentSubjectAutocomplete` for user, subuser, and customer search functionality.
- Update i18n phrases for channel selector and subject assignment.
- Enhance unit and E2E tests for release channel availability, switching, and runtime configuration.
- Modify modules for channel-related state handling and runtime refresh mechanics.
