Fix Python 3.14 SyntaxWarning: 'return' in 'finally' block

[Copilot]

Python 3.14 (PEP 765) emits SyntaxWarning for return inside finally blocks, since it silently suppresses exceptions. Seven vehicle data parsers trigger this on every Home Assistant startup.

Moved return retval from inside finally to after the try/except block in all affected files:

• vehicle/battery.py
• vehicle/climate.py
• vehicle/maintenance.py
• vehicle/position.py
• vehicle/running.py
• vehicle/safety.py
• vehicle/tires.py

Before:

try:
    ...
except KeyError as e:
    _LOGGER.info(f"... info not available: {e}")
finally:
    return retval

After:

try:
    ...
except KeyError as e:
    _LOGGER.info(f"... info not available: {e}")
return retval

Behavior is preserved — retval is always returned whether parsing succeeds or a KeyError is caught. The difference is that unexpected exceptions (not KeyError) will now properly propagate instead of being silently swallowed.

Pull request overview

This PR updates several vehicle data parsers to avoid Python 3.14 SyntaxWarning about return statements inside finally blocks, by moving the return retval to after the try/except so unexpected exceptions are no longer implicitly suppressed.

Changes:

• Removed finally: return retval patterns in 7 vehicle parsers and replaced with return retval after the try/except.
• Ensured KeyError continues to be handled gracefully while allowing other exceptions to propagate (with one noted inconsistency in battery.py).
