fix: apply tag removal and source stripping to root-level plugin files

The deploy workflow reads from the repo root (admin/, includes/, public/),
not the peptide-news-plugin/ subdirectory. Applied the same changes:
- Removed Tag component and tag rendering from ArticleCard
- Removed all tag-related CSS (variables, styles, skeleton, responsive)
- Added strip_source_suffix() to REST API for cleaning source names
  from titles/summaries with case-insensitive and domain-based matching
