refactor: migrate all icons from Untitled UI to FontAwesome Pro Duotone

Replace all @untitledui/icons imports across 55 files with equivalent
@fortawesome/pro-duotone-svg-icons icons, using FontAwesomeIcon wrappers
(FC<{ className?: string }>) for prop-based usage and inline replacements
for direct JSX usage. Drops unsupported Untitled UI-specific props
(strokeWidth, numeric size). TypeScript compiles clean with no errors.
