Extract hardcoded rgba colors and inline styles to CSS classes

- Add .inline-error and .inline-warning utility classes to dashboard.css
  with correctly-matched terminal palette rgba values (replaces off-palette
  rgba(231,76,60,0.1) and rgba(241,196,15,0.1))
- Add .key-generated-alert class for the new API key display frame
- Add base .dependency-item, .dependency-group h4, .dependency-item a,
  .dependency-title, .btn-small overrides to ticket.css
- Remove all inline styles from the dependency list template in ticket.js
  — layout, colors, and sizing now come from CSS classes
- Update CreateTicketView.php and ApiKeysView.php to use the new classes
