[Network] Expose WAF rule paranoiaLevel and rule set displayName

### Preconditions

- [x] No need to upgrade Python SDK or the Python SDK is ready.

### Related command

az network application-gateway waf-config list-rule-sets

az network application-gateway waf-config list-dynamic-rule-sets

### Resource Provider

Microsoft.Network/applicationGateways

### Description of Feature or Work Requested

Two new read-only fields in api-version 2026-01-01:

1. paranoiaLevel on each managed rule (ApplicationGatewayFirewallRule). Values PL1 to PL4. It is the OWASP CRS paranoia level of the rule, where PL1 is baseline detection and PL4 is strictest. Set only for DRS and OWASP rule sets. Customers need it to understand why a rule fires and whether to disable it.

2. displayName on the rule set (ApplicationGatewayFirewallRuleSetPropertiesFormat). For example "Default Ruleset 2.2 (Latest, Recommended)" or "Core Ruleset 3.0 (Deprecated)". Today the CLI only shows ruleSetType and ruleSetVersion, for example OWASP 3.0, so customers cannot tell which version is current and which is deprecated.

Both are output only. No new parameters and no behavior change.
