Summary

This PR refactors the k-space conversion stack and applies a broad cleanup across related utilities, docs,
and tests.

What changed

• moved convert_to_kspace out of utilities.conversion.core into utilities.conversion.api
• split lower-level coordinate conversion responsibilities into more focused modules
• updated package exports and API references to match the new conversion entry point
• cleaned up analysis and accessor utilities, including _bin behavior and meshgrid-related helpers
• improved plotting utilities, especially colorbar removal behavior
• applied Ruff- and typing-driven fixes across analysis, fitting, plotting, conversion, and loader code
• updated tests to reflect the refactors and adjusted a few expected numeric values
• refreshed documentation links, Sphinx configuration, API docs, and changelog scaffolding
• migrated uv development dependencies to dependency groups

Notes

Most of the changes are structural and maintenance-oriented, but they also improve API clarity around
momentum-space conversion and reduce documentation/test noise.
