[AI-8th] add Spring Boot configuration metadata support

[pmupkin]

This PR(related issue #1404) adds Spring Boot configuration metadata support for SOFABoot IDE auto-completion.

Changes

1. Added additional-spring-configuration-metadata.json to sofa-boot-autoconfigure

• Covers RPC, Runtime, ISLE, Ark, and Tracer configuration properties.
• Adds descriptions, defaults, value hints, and conditional auto-configuration switches.
• Adds metadata for Tracer integration toggles such as Kafka, Redis, RabbitMQ, RocketMQ, Zipkin, Spring MVC, and others.
• Ignores sofa.boot.rpc.environment, which is injected internally and should not be exposed as a user-facing configuration property.
• Added additional-spring-configuration-metadata.json to sofa-boot-actuator-autoconfigure

2. Covers health check, startup, and virtual-thread startup configuration metadata.

• Adds default values and hints for health status mapping/order.
• Added metadata validation tests for both modules

3. Verifies additional metadata structure.

• Verifies expected groups, properties, and hints.
• Verifies generated spring-configuration-metadata.json contains merged metadata items.
