feat(apps): Migrate all apps to Spring AI 2.0 and Spring Boot 4.1 (#909)

Upgrade every Maven module to Spring Boot 4.1.0 and consolidate all
Spring AI usage on the 2.0.0 GA release (previously a mix of 1.1.7,
2.0.0-M6 and 2.0.0-RC2). Fix the breaking changes surfaced by the
upgrade:

- Rename artifact spring-ai-advisors-vector-store to
  spring-ai-vector-store-advisor.
- Move @mcptool from org.springaicommunity.mcp.annotation to
  org.springframework.ai.mcp.annotation.
- Replace removed McpSyncClientCustomizer with the generic
  McpClientCustomizer<McpClient.SyncSpec>.
- Replace removed PromptChatMemoryAdvisor with MessageChatMemoryAdvisor.
- ChatClient.Builder.defaultOptions now takes a ChatOptions.Builder
  instead of a built ChatOptions; update call sites and tests.
- OllamaChatModel.Builder.defaultOptions renamed to options.
- Migrate direct Jackson databind usage to Jackson 3 (tools.jackson)
  where Spring AI 2.0 no longer brings Jackson 2 transitively.

All 23 modules compile (mvn clean test-compile) and the affected unit
tests pass.

Also improve the Dependabot config: group Spring, Maven plugins, test
tooling, Kubernetes, Docker images and GitHub Actions so coordinated
upgrades arrive as single reviewable PRs instead of dozens.
