Dustin Healy f101d73f72 fix(mcp): resolve apps per request, tighten resource templates, extract app controller
Resolve mcpSettings.apps per request through the tenant-scoped allowlist resolver (inheriting the
YAML base when omitted) and consult it in callTool: when a tenant/role/user has apps disabled, the
tool result is returned with no UI resource attached, so those users no longer get a broken iframe
that the gated app endpoints reject. The OAuth-path connection advertises the resolved value.

Constrain query and query-continuation URI-template operators to their declared variable names
instead of the whole query string, so a template like file://items{?id} no longer authorizes
unrelated query parameters such as ?admin=true. The path-traversal guard still applies.

Move the MCP Apps per-endpoint validation and orchestration into packages/api as TypeScript
service functions (readAppResource, listAppResources, listAppResourceTemplates, callAppTool)
exported from @librechat/api, delegating through a structural manager interface to avoid a circular
import. The /api controllers become thin adapters; resolveAppContext, the sandbox file serve, and
the requireMCPAppsEnabled middleware stay in /api as request-bound glue.
