🔬 ci: Add TypeScript Type Checks to Backend Workflow and Fix All Type Errors (#12451)

* fix(data-schemas): resolve TypeScript strict type check errors in source files - Constrain ConfigSection to string keys via `string & keyof TCustomConfig` - Replace broken `z` import from data-provider with TCustomConfig derivation - Add `_id: Types.ObjectId` to IUser matching other Document interfaces - Add `federatedTokens` and `openidTokens` optional fields to IUser - Type mongoose model accessors as `Model<IRole>` and `Model<IUser>` - Widen `getPremiumRate` param to accept `number | null` - Widen `bulkWriteAclEntries` ops to untyped `AnyBulkWriteOperation[]` - Fix `getUserPrincipals` return type to use `PrincipalType` enum - Add non-null assertions for `connection.db` in migration files - Import DailyRotateFile constructor directly instead of relying on broken module augmentation across mismatched node_modules trees - Add winston-daily-rotate-file as devDependency for type resolution * fix(data-schemas): resolve TypeScript type errors in test files - Replace arbitrary test keys with valid TCustomConfig properties in config.spec - Use non-null assertions for permission objects in role.methods.spec - Replace `.SHARED_GLOBAL` access with `.not.toHaveProperty()` for legacy field - Add non-null assertions for balance, writeRate, readRate in spendTokens.spec - Update mock user _id to use ObjectId in user.test - Remove unused Schema import in tenantIndexes.spec * fix(api): resolve TypeScript strict type check errors across source and test files - Widen getUserPrincipals dep type in capabilities middleware - Fix federatedTokens type in createSafeUser return - Use proper mock req type for read-only properties in preAuthTenant.spec - Replace `as IUser` casts with ObjectId-typed mocks in openid/oidc specs - Use TokenExchangeMethodEnum values instead of string literals in MCP specs - Fix SessionStore type compatibility in sessionCache specs - Replace `catch (error: any)` with `(error as Error)` in redis specs - Remove invalid properties from test data in initialize and MCP specs - Add String.prototype.isWellFormed declaration for sanitizeTitle spec * fix(client): resolve TypeScript type errors in shared client components - Add default values for destructured bindings in OGDialogTemplate - Replace broken ExtendedFile import with inline type in FileIcon * ci: add TypeScript type-check job to backend review workflow Add a `typecheck` job that runs `tsc --noEmit` on all four TypeScript workspaces (data-provider, data-schemas, @librechat/api, @librechat/client) after the build step. Catches type errors that rollup builds may miss. * fix(data-schemas): add local type declaration for DailyRotateFile transport The `winston-daily-rotate-file` package ships a module augmentation for `winston/lib/winston/transports`, but it fails when winston and winston-daily-rotate-file resolve from different node_modules trees (which happens in this monorepo due to npm hoisting). Add a local `.d.ts` declaration that augments the same module path from within data-schemas' compilation unit, so `tsc --noEmit` passes while keeping the original runtime pattern (`new winston.transports.DailyRotateFile`). * fix: address code review findings from PR #12451 - Restore typed `AnyBulkWriteOperation<AclEntry>[]` on bulkWriteAclEntries, cast to untyped only at the tenantSafeBulkWrite call site (Finding 1) - Type `findUser` model accessor consistently with `findUsers` (Finding 2) - Replace inline `import('mongoose').ClientSession` with top-level import type - Use `toHaveLength` for spy assertions in playwright-expect spec file - Replace numbered Record casts with `.not.toHaveProperty()` in role.methods.spec for SHARED_GLOBAL assertions - Use per-test ObjectIds instead of shared testUserId in openid.spec - Replace inline `import()` type annotations with top-level SessionData import in sessionCache spec - Remove extraneous blank line in user.ts searchUsers * refactor: address remaining review findings (4–7) - Extract OIDCTokens interface in user.ts; deduplicate across IUser fields and oidc.ts FederatedTokens (Finding 4) - Move String.isWellFormed declaration from spec file to project-level src/types/es2024-string.d.ts (Finding 5) - Replace verbose `= undefined` defaults in OGDialogTemplate with null coalescing pattern (Finding 6) - Replace `Record<string, unknown>` TestConfig with named interface containing explicit test fields (Finding 7)
