Python 3.14 Support

[Bastian-Krause]

Description
The release of Python 3.14 is scheduled for 2025-10-07. This PR is meant to track what's left to be done until we can advertise Python 3.14 support in labgrid.

labgrid itself:

• remote/coordinator: drop returns from finally clauses #1722 (SyntaxWarning: 'return' in a 'finally' block)
• either "cannot determine default role" for inline interpreted text without role sphinx-doc/sphinx#13904 or documentation fixes in labgrid (PR pending)

Dependencies:

• grpcio: Release with Python 3.14 support (multiple critical exceptions)
• python-kasa (kasa extra) -> mashumaro: Release with Add support for Python 3.14 Fatal1ty/mashumaro#285 (mashumaro.exceptions.UnserializableField: Field "login_version" of type Optional[int] in DeviceConnectionParameters is not serializable)
• sphinx (doc extra): Release with Followup-to: Fix tests for Python 3.14a7+ (#13514) sphinx-doc/sphinx#13527 (AttributeError: __annotate_func__)
• rstcheck -> rstcheck-core -> pydantic (CI only): v2.12 release with Add initial support for Python 3.14 pydantic/pydantic#11991 (no installable version)
• pyusb: Release with a fix for DeprecationWarning on Python 3.14 due to non-zero _pack_ pyusb/pyusb#535 (DeprecationWarning: Due to '_pack_', the '_usb_descriptor_header' Structure will use memory layout compatible with MSVC (Windows). If this is intended, set _layout_ to 'ms'. The implicit default is deprecated and slated to become an error in Python 3.19.)
