- problem: `addImageUrls` had a side effect that was being leveraged before to populate both the `ocr` message field, now `fileContext`, and `client.options.attachments`, which would record the user's uploaded message attachments to the user message when saved to the database and returned at the end of the request lifecycle
- solution: created dedicated handling for file context, and made sure to populate `allFiles` with non-provider attachments

📁 feat: Send Attachments Directly to Provider (OpenAI) (#9098)
* refactor: change references from direct upload to direct attach to better reflect functionality

* fix: respect server's token endpoint auth methods for MCP OAuth refresh
Previously, LibreChat always used Basic Auth when refreshing OAuth tokens if a
client_secret was present. This caused issues with servers (like FastMCP) that
only support client_secret_post. Now properly checks and respects the server's
advertised token_endpoint_auth_methods_supported.
Fixes token refresh failures with error: "refresh_token.client_id: Field required"
* chore: remove MCP OAuth URL Logging
* WIP: conversion of `ocr` to `context`
* refactor: make `primeResources` backwards-compatible for `ocr` tool_resources

- Refactored social login to validate email domains before checking for existing users, improving registration flow.
* refactor: Email Domain Validation in LDAP and Social Login Strategies
* Remove unused STATIC_CONFIG and LIBRECHAT_YAML_CONFIG cache keys.
These cache keys were identified as dead code - they were being written to but never read from anywhere in the codebase after a recent refactor:
- STATIC_CONFIG was used as a cache namespace that stored configuration data
- LIBRECHAT_YAML_CONFIG was the key used within that namespace to store parsed YAML config
- The cache.set() operation in loadCustomConfig.js stored the config but no cache.get() operations retrieved it
- Configuration data is already handled through other mechanisms without caching
* # removed tests regarding cache
- This allows use APP_CONFIG in FORCED_IN_MEMORY_CACHE_NAMESPACES
- Remove the complexity of nested namespace (e.g. we no longer have to worry about the prefix of every role key)
