refactor: remove all bold font weights from UI/UX (291 replacements)

Replace font-bold, font-black, and font-semibold with font-normal throughout:
- 26 component files
- 1 CSS utility file (globals.css)
- 291 total occurrences

Text hierarchy now maintained through font-size differences only.
All tests passing (291/291).
