Fix version determination logic for workflow_call

The bug: When pypi-publish-agent is called via workflow_call from
bump-version, github.event_name is "workflow_dispatch" (inherited
from parent), NOT "workflow_call". This caused the code to check
github.event.inputs.version (empty) instead of inputs.version (0.4.44).

The fix: Check inputs.version first, before checking event_name.
This works correctly for:
- workflow_call: uses inputs.version
- Tag push: extracts from tag
- workflow_dispatch with version param: uses inputs.version
- workflow_dispatch event UI: uses event.inputs.version

Debug output showed:
- Event name: workflow_dispatch
- Input version: 0.4.44 (correct!)
- Workflow dispatch version: (empty)
- Final VERSION= (bug - used wrong source)

Now it will use inputs.version first, giving VERSION=0.4.44.
