♻️ refactor(helpers): standardize file naming conventions and improve code organization

- Rename files to follow camelCase naming convention:
  • auth-header.js → authUtils.js
  • other.js → logUtils.js
  • rehypeSplitWordsIntoSpans.js → textAnimationUtils.js

- Update import paths in affected components:
  • Update exports in helpers/index.js
  • Fix import in LogsTable.js for logUtils
  • Fix import in MarkdownRenderer.js for textAnimationUtils

- Remove old files after successful migration

- Improve file naming clarity:
  • authUtils.js better describes authentication utilities
  • logUtils.js clearly indicates log processing functions
  • textAnimationUtils.js concisely describes text animation functionality

This refactoring enhances code maintainability and follows consistent naming patterns throughout the helpers directory.
