🆕 feat: Enhanced Title Generation Config Options (#8580)

* 🏗️ refactor: Extract reasoning key logic into separate function

* refactor: Ensure `overrideProvider` is always defined in `getProviderConfig` result, and only used in `initializeAgent` if different from `agent.provider`

* feat: new title configuration options across services

- titlePrompt
- titleEndpoint
- titlePromptTemplate
- new "completion" titleMethod (new default)

* chore: update @librechat/agents and conform openai version to prevent SDK errors

* chore: add form-data package as a dependency and override to v4.0.4 to address CVE-2025-7783

* feat: add support for 'all' endpoint configuration in AppService and corresponding tests

* refactor: replace HttpsProxyAgent with ProxyAgent from undici for improved proxy handling in assistant initialization

* chore: update frontend review workflow to limit package paths to data-provider

* chore: update backend review workflow to include all package paths
