feat(FR-2451): add Prometheus Query Preset delete confirmation

[agatha197]

Resolves #6357 (FR-2451)

Stacked on top of #7085.

Summary

Adds a destructive Delete action to each row of the Prometheus Query Preset table, gated by a typed-confirmation modal as required by .claude/rules/destructive-confirmation.md.

• Adds an action column (general.Control) on the right side of PrometheusQueryPresetList with a danger DeleteOutlined icon button. The list now accepts an onDeletePreset(row) callback prop.
• Mounts the delete flow at the orchestrator level (AutoScalingRulePresetTab), mirroring the editor-modal mount pattern from Sub-task 3. Clicking Delete sets a { id, name } target; the orchestrator renders a single BAIConfirmModalWithInput whose OK button only enables once the user types the preset's exact name.
• Adds AutoScalingRulePresetTabDeleteMutation calling adminDeletePrometheusQueryPreset(id: ID!). On success: message.success toast + updateFetchKey() to refetch the list. On error: per-error toast and modal closes (matches ResourcePresetList.tsx convention).
• Per .claude/rules/destructive-confirmation.md, Popconfirm / single-click modal.confirm are not used — only BAIConfirmModalWithInput.

i18n keys added (under prometheusQueryPreset.*)

• PermanentlyDeletePreset — modal title with {{ name }} interpolation
• DeleteWarning — warning content shown in the modal Alert
• SuccessfullyDeleted — success toast

Existing keys reused: button.Delete, general.Control, dialog.TypeNameToConfirmDeletion.
