[Az.FrontDoor] Expose DisplayName, Status, and per-rule ParanoiaLevel

### Description of the new feature

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. `Az.FrontDoor` is generated from API version `2025-11-01`, so `Get-AzFrontDoorWafManagedRuleSetDefinition` does not expose them.

For example, the API returns `Default Ruleset 2.2 (Latest, Recommended)`, status `GA`, and a `paranoiaLevel` value on each DRS rule.

### Request

Regenerate `Az.FrontDoor` against API version `2026-04-01` and expose `DisplayName`, `Status`, and per-rule `ParanoiaLevel` in the output of `Get-AzFrontDoorWafManagedRuleSetDefinition`.

### Reference

Start with Get-AzFrontDoorWafManagedRuleSetDefinition and the Az.FrontDoor generation inputs for API version 2026-04-01; review merged spec PR 42373 and release plan 36510. Done means the cmdlet output exposes DisplayName and Status for managed rule-set versions and ParanoiaLevel for each rule.
