Remove remaining HOPP integration and references

This PR builds upon #825 and #826; those should be merged in before this one.

This PR removes remaining HOPP integration from H2Integrate and migrates the last active
HOPP-backed example path to native H2I components.

Summary of changes:

1. Remove the hopp dependency from the project dependency stack.
2. Remove HOPP component registration and related model-assembly logic.
3. Remove HOPP converter modules and HOPP-specific tests.
4. Replace example 25 sizing mode inputs to use a native electricity feedstock source.
5. Remove all HOPP references from active docs, templates, and example narratives.
6. Update tests/imports that relied on HOPP utility functions or constants.
