Pull request overview

Adds English i18n strings needed for the Deployments UI, establishing initial deployment.* and replicaStatus.* namespaces and wiring new menu labels.

Changes:

• Add a new deployment namespace with labels/messages for deployment creation, configuration, status, and navigation.
• Add a new top-level replicaStatus namespace with status labels and tooltip texts.
• Add webui.menu entries for “Deployments” and “Admin Deployments”.

[Copilot]

New i18n keys are added only to en.json. None of the other locale files under resources/i18n/ contain the new "deployment" / "replicaStatus" namespaces, so non-English locales will be missing these keys at runtime. Please run the repo’s i18n scanner (make i18n / i18next-scanner) and commit the updated locale JSONs (at least adding NOT_TRANSLATED placeholders for other languages).

[Copilot]

The PR description still contains unresolved placeholders (e.g., “resolves #NNN (FR-MMM)” and checklist/template items). Please update the PR description with the actual issue/Jira references and concrete review/testing notes so the change can be traced and reviewed properly.
