feat: support multiline patterns in switch rule conditions

- HostWildcardCondition, UrlWildcardCondition, HostRegexCondition,
  UrlRegexCondition now accept newline-separated patterns in addition
  to pipe-separated ones
- Replace pattern input with expandable textarea (1 row collapsed,
  10 rows expanded) with toggle button
- Single-line mode blocks Enter key and auto-expands on click when
  multiline content exists
- validateCondition validates each line independently for regex types
