[front-door] Expose DisplayName, Status, and per-rule ParanoiaLevel in managed rule-set output

### Command

`az network front-door waf-policy managed-rule-definition list`

### Problem

The Front Door managed rule-set manifest now returns these read-only fields in API version `2026-04-01`:

- `properties.displayName`: display name for each managed rule-set version
- `properties.status`: lifecycle status such as `GA`, `Preview`, or `Deprecated`
- `properties.ruleGroups[].rules[].paranoiaLevel`: `PL1` through `PL4` for each DRS rule

The service already returns all three fields. The current `front-door` extension uses API version `2025-11-01`, and its generated response schema does not include them. As a result, the CLI output drops the fields.

For example, the API returns `Default Ruleset 2.2 (Latest, Recommended)`, status `GA`, and a `paranoiaLevel` value on each DRS rule. The CLI output contains none of these values.

### Request

Regenerate the `front-door` extension against API version `2026-04-01` and expose all three fields in the output of `managed-rule-definition list`.
