Update RBAC management docs to follow up on FR-2479/FR-2819/FR-2825 confirmation modal rework

[ironAiken2]

Background

The RBAC management user manual is being updated in PR #7446 (docs(rbac): align with revoke/remove confirmation flow and localized scope names). The new copy documents:

• Delete a Permission → Remove a Permission (popconfirm UX)
• Remove Users from a Role → Revoke Users from a Role (popconfirm UX)
• The convention: "this action is treated as reversible and uses a lightweight popup confirmation rather than a typed-name confirmation modal"

This convention is exactly the one codified in .claude/rules/destructive-confirmation.md (FR-2479) and currently being rolled out across the project by FR-2819 (typed modal for irreversible deletes) and FR-2825 (Popconfirm for reversible activate/deactivate / revoke).

Scope

Verify and, if needed, supplement the docs so that the RBAC manual matches what FR-2819 / FR-2825 actually ship:

• Confirm the screenshots in docs(rbac): align with revoke/remove confirmation flow and localized scope names #7446 (rbac_revoke_popconfirm.png, rbac_permission_modal.png) match the current popconfirm + modal copy after FR-2825 lands.
• Cross-check button labels ("Remove Permission", "Revoke User") against the code so the doc and UI agree.
• Add any RBAC-side flow that FR-2819/FR-2825 changed but docs(rbac): align with revoke/remove confirmation flow and localized scope names #7446 did not catch (e.g., role-level destructive actions that should be using the typed modal vs. popconfirm).
• Touch all 4 language variants (en/ja/ko/th) where docs(rbac): align with revoke/remove confirmation flow and localized scope names #7446 added content.

Out of scope

• Re-litigating the confirmation UX rule itself — that is settled (FR-2479).
• Code changes to the RBAC pages — those belong to FR-2819 / FR-2825.
