fix: update codespell config to ignore false positives

- Exclude minified JS files (bundle.js, *.min.js) from spelling checks
- Exclude .bib files from end-of-file-fixer (bibtex-tidy handles them)
- Add ignore words for: variable names (currentY, initialY), Python
  methods (assertIn), acronyms (SER, ALS), and valid technical terms
- Skip .tex files from codespell
