Subject: [PATCH] feat: add powershell curl tab to UI (#8889)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* chore: Bump version to 1.5.0 and update dependencies

- Updated langflow version to 1.5.0 in pyproject.toml, package.json, and package-lock.json.
- Updated langflow-base dependency to version 0.5.0.
- Added platform markers for several dependencies in uv.lock to improve compatibility across different systems.

* fix: fixes auth check for auto_login  (#8796)

* ref: improve docling template updates and error message (#8837)

Co-authored-by: Gabriel Luiz Freitas Almeida <gabriel@langflow.org>

* Attempt to provide powershell curl command

* [autofix.ci] apply automated fixes

* [autofix.ci] apply automated fixes (attempt 2/3)

* Added OS selector to code tabs

* Added no select classes to API modal

* ✨ (code-tabs.tsx): add data-testid attribute to API tab elements for testing purposes
🔧 (tweaksTest.spec.ts, curlApiGeneration.spec.ts, pythonApiGeneration.spec.ts, generalBugs-shard-3.spec.ts): update test scripts to use data-testid attribute for API tab elements instead of role attribute
