Branch: fix/8653-daily-report-category-highlight

  Staged changes:
  - Added import for mekhq.MekHQ
  - Removed hardcoded DAILY_REPORT_DATE_FORMAT constant
  - Updated isDateOnly() to use user's configured date format and locale via
  MekHQ.getMHQOptions().getLongDisplayDateFormat() and MekHQ.getMHQOptions().getDateLocale()
