refactor(ui): replace inline INPUT_CLS/LABEL_CLS/BTN_DANGER constants and action link classes with CSS component classes

Remove duplicated Tailwind class string constants from 15 component files.
Use app-input, app-select, app-label, app-action-danger-btn, and
app-action-delete CSS component classes from globals.css instead.
