fix: 6 UX regressions — popups, themes, cursor, selection, status bar

Cursor blinking:
- handleFocus() was referenced in TerminalView template but never
  defined in script — clicking the terminal container threw a runtime
  error preventing focus. Added the missing function.
- Removed duplicate handleFocus at end of file

Tool windows:
- CSP simplified for macOS WKWebView compatibility. Previous CSP
  was blocking child WebviewWindow IPC initialization.

RDP tab switch:
- Added rdp_force_refresh command that marks frame_dirty=true and
  clears dirty region, forcing next get_frame to return full buffer
- Called on tab activation and after resize completion
- Eliminates 4-5 second wait for "keyframe" when switching tabs
